Is it still there somewhere?
The Louies got out of the business. Their cookies were delicious but
couldn't compete with imports. They found a Chinese food magnate in
Brazil who wanted the machines so they disassembled them, marked every
piece (sort of like the old London Bridge) and reassembled them in
Brazil. They left us with outrageous 3-phase power and natural gas
feeds.

At least his invention lives on and hopefully he got a nice vacation in
Brazil out of it.

We had Japanese for lunch, too, unagi and salmon rolls, but no beer

But then how could I ever buy you burger and beer at Zeitgeist?

Sleep after lunch, of course.

You da boss, so you can do that

At least that's what George Jefferson said after he opened his chain of
cleaning stores and moved into that ritzy apartement.

Why would that bother me? You seem to be OK at linear IC design.

I think we buy one part from AZM, a PECL/TTL converter, and few of
those. The rest of their stuff is too slow. And we don't do much ECL
any more; the gates inside an FPGA are a lot faster at 1/1000 the
cost.

And I wouldn't use that AZM part in a new design; there are faster and
cheaper ways to do it.

John

Have you used any of the SiGe logic parts? eg.

http://www.onsemi.com/pub_link/Collateral/NBSG86A-D.PDF

40ps rise/fall.

And the rise/fall times are in the datasheet, in contrast to regular logic.

isn't that what the ibis models are for?

Gate driver chips are cool, though. They have lots of

Oh yeah


Of course the ideal scenario would be a push-pull MMIC with
15V or more
supply voltage but that ain't going to happen. Same with RF
switches,
even if they could take 12V they are surprisingly slow in
switch action.

Ok, could roll my own, of course. But that gets to be
involved and a bit
too big for this project.
What's the load? Need DC coupling/long pulses?

Pulses are under 100nsec length and duty cycle is well under
5%. Getting
DC across would be great but I am afraid I'll have to clamp
that ...
somehow ... because it's a high voltage I'll have to move with
that. Or
I'll let this whole thing ride on the rail. Woe to dose who

I know how to get 6 or 7 volts of brutal sub-ns swing cheap,
at zero
Iq. Could be doubled, depending. Not for public release.

7V would be a bit low, and I'd need zippy in both directions.
If you need high-side drive, a pair of my drivers could feed
opposite
ends of a 1:1 transmission line transformer (or maybe a balun) to
double the swing. 12 volts for 100 ns would be no problem,
edges well
below a ns.

RF parts such as baluns or obscure directional couplers with a
voodoo
coefficient never scared me.


At below 5% duty cycle, you probably don't need to DC restore.

Not sure yet if I do. This high voltages acts as kind of a
reference
somewhere. It's one of those circuits that most people won't
even touch
with a 10ft pole.


It'll cost you a burger and a couple of beers. Zeitgeist has

Now if you ever get into this area we have a very nice Japanese

If pulse width is fixed, there's another way to do it: a really
fast
open-drain mosfet feeding a 1:1 transformer, 12 volts or
whatever you
like. The magnetizing current powers the falling edge. Also cheap.

It must remain adjustable.
Never turn down an offer from Larkin. He's promised you a

I am sure he can. Fast stuff is what his company mostly does and
if they
didn't earn megabucks per year with this they would hardly be able to
buy a large building smack dab in the middle of a metropolis.
It was a working fortune cookie factory. 1930's (ie, terrible)
concrete side walls, wooden floors and roof, a perfect candidate for
pancaking in the next good earthquake. It's sitting on sand, at the
edge of a liquefaction zone. We added a bunch of concrete footings and
steel frames and plywood and bolts.

You can see our place in the default Google Earth view of San
Francisco. For some odd reason, Google thinks "San Francisco" is in
the middle of the interesction of Market and Van Ness, one block away.

And we haven't had a sandstorm for as long as we've been here.

Those cherubim were on there before you bought it? They are amazingly
well preserved. I can't imagine the salty air down there to be too
friendly to concrete and plaster. The almond below probably has some
cultural meaning as well.

They are original, and we just cleaned them up and repainted. No
architect would dare do anything this cool any more.

The salty fog is out west, near the ocean. Everything rusts out there.

The bummer is that it's a wooden building that looks up at Sutro
Tower, 22 megawatts of AM/FM/TV/whatever. The EMI is ghastly.


Look at the bright side: If you'd need a sensor somewhere out of reach
of power you can just add a loop, some diodes, and it'll be supplied
with power until Sutro Tower keels over

If I'd needed a quiet lab place I'd find something in the outbacks of
Alabama or similar states. Then you are neither bothered by RF fields
nor by biz-hostile politicians.

On the other hand, the chances of being able to hire locally resident
expert help wouldn't be that great.


Near Huntsville? You've got to be kidding ...

Slowman is never shy about his ignorance.

Presumably krw wouldn't know about John Christy and Roy Spencer at the
University of Alabama at Huntsville, and wouldn't understand the
significance of their antics if he did.

I don't have much ignorance to be shy about, and krw has an over-supply
- for one thing he doesn't appreciate how little he actually knows.

It must really stick in his craw when he learned that a good many of the
ECL/PECL parts he buys from AZMicrotek were designed by yours truly ;-)

A second-source for the Motorola/ON-Semiconductor originals ...
Jim-out-of-touch-reality-Thompson will probably tell us that his
versions are actually improved second-sources, which might even be true
whenever AZMicrotek have a better process than Motorola.

Sadly, as Hericalitus might have said if he had lived long enough,
successive batches of chips never go through exactly the same process.

Near Huntsville? You've got to be kidding ...

The University of Alabama at Huntsville (UAH) has a certain fame amongst
people who are persuaded by the evidence for anthropogenic global warming.
Two of the researchers there - Spencer and Christy - were a bit slow to
correct their satellite data for orbital decay, and for a while their
uncorrected figures deviated from the predictions of the climate models.

http://en.wikipedia.org/wiki/Satellite_temperature_measurements

Roy Spencer is a card-carrying fundamentalist, and John Christy has spent
time as a bi-vocatiinal mission-pastor. This may - in part - explain why
they are two of the nine top climate scientists (out of the top 300) who
aren't persuaded by the evidence for anthropogenic global warming. Maybe
they think a loving God couldn't be that mean.

http://www.sourcewatch.org/index.php?title=Roy_Spencer

http://www.sourcewatch.org/index.php?title=John_R._Christy

Their kind of expertise can't entirely be relied on

... And they are Baptists - perhaps not
as sincerely Baptist as the inhabitants of Urk are Calvinist, but still
pretty inflexible - so you'd run the risk of being rejected as a
schismatic Lutheran.

Baptists and Lutherans get along quite well, and I love their choirs.
They can make the rafters shake.

Unfortunately, that kind of belief can gnaw at the foundations as well as
shaking the rafters.

Have to drive around a hundred pF or so in parallel with maybe a few
hundred ohms blazingly fast. 10-12V amplitude, transitions ideally
sub-nanosecond from 10-90% both directions. Not too boutiquish or
unobtanium (which excludes certain companies ...) and not more than a
few Dollars. Shouldn't introduce noise when low. Low quiescent current,
preferably under 20mA.

Looked around and the fastest one I could see is this dude:

http://www.diodes.com/datasheets/ZXGD3003E6.pdf

Not too much data but it gets into the 2nsec range. Anyone aware of a
driver with even more testosterone?
The rise/fall times are mediocre. A little series inductive peaking
would help.

Mediocre? At high capacitive load maybe but at low loads I think they
are amazing for a 25c part. Most others including its other ZXGD300x
brethren peter out towards 10nsec for one of both slopes towards zero
capacitance.


Gate driver chips are cool, though. They have lots of off-label uses.

Oh yeah


Of course the ideal scenario would be a push-pull MMIC with 15V or more
supply voltage but that ain't going to happen. Same with RF switches,
even if they could take 12V they are surprisingly slow in switch action.

Ok, could roll my own, of course. But that gets to be involved and a bit
too big for this project.
What's the load? Need DC coupling/long pulses?

Pulses are under 100nsec length and duty cycle is well under 5%. Getting
DC across would be great but I am afraid I'll have to clamp that ...
somehow ... because it's a high voltage I'll have to move with that. Or
I'll let this whole thing ride on the rail. Woe to dose who toucha wid
da fingahs


I know how to get 6 or 7 volts of brutal sub-ns swing cheap, at zero
Iq. Could be doubled, depending. Not for public release.

7V would be a bit low, and I'd need zippy in both directions.
If you need high-side drive, a pair of my drivers could feed opposite
ends of a 1:1 transmission line transformer (or maybe a balun) to
double the swing. 12 volts for 100 ns would be no problem, edges well
below a ns.

RF parts such as baluns or obscure directional couplers with a voodoo
coefficient never scared me.


At below 5% duty cycle, you probably don't need to DC restore.

Not sure yet if I do. This high voltages acts as kind of a reference
somewhere. It's one of those circuits that most people won't even touch
with a 10ft pole.


It'll cost you a burger and a couple of beers. Zeitgeist has about 40
on tap.

I am game. But I have no idea when I get to S.F. the next time. A lot of
my clients are no longer in California, for reasons we all know, and
Villaraigosa has just made that loud and clear to companies once more :-(

Now if you ever get into this area we have a very nice Japanese
restaurant. Blue Moon and Sapporo on tap.


If pulse width is fixed, there's another way to do it: a really fast
open-drain mosfet feeding a 1:1 transformer, 12 volts or whatever you
like. The magnetizing current powers the falling edge. Also cheap.

It must remain adjustable.

Never turn down an offer from Larkin. He's promised you a half-fast solution,
and I'm sure he can deliver ;-)


I am sure he can. Fast stuff is what his company mostly does and if they
didn't earn megabucks per year with this they would hardly be able to
buy a large building smack dab in the middle of a metropolis.

It must really stick in his craw when he learned that a good many of the
ECL/PECL parts he buys from AZMicrotek were designed by yours truly ;-)

A second-source for the Motorola/ON-Semiconductor originals ...
Jim-out-of-touch-reality-Thompson will probably tell us that his
versions are actually improved second-sources, which might even be true
whenever AZMicrotek have a better process than Motorola.

The AZ version of the 100ELT21 is actually a lot better than the
original Moto design, in the sense that the Moto arguably had a bug
and the AZ didn't. I actually did some comparative measurements for
the guys at AZ, because I had a scope that could measure ps jitter,
and they didn't.

Jim is a jerk, but if anybody is out of touch about IC design, it
isn't him: it's you.

Sadly, as Hericalitus might have said if he had lived long enough,
successive batches of chips never go through exactly the same process.

Fathead.

I concede that even Jim could come up with something better than a

the bug before he started his design.

I actually did some comparative measurements for
the guys at AZ, because I had a scope that could measure ps jitter,

That doesn't say anything good about AZMicrotek. Back around 1990 I
persuaded Cambridge Instruments to buy a decent Tek sampling scope to
measure sub-nanosecond jitter - we were paying the earth for Gigabit
Logic's GaAs logic, and even our managers could be persuaded the you
needed measuring gear that could see if it was meeting its
specification. The kind of cheapskates who would skimp on measuring gear
capable of doing proper quality control on what they were making aren't
going to hire the best linear designer in the business, but the cheapest ...

Jim is a jerk, but if anybody is out of touch about IC design, it
isn't him: it's you.

I've never claimed to be in touch with IC design, but I've used some of
the ICs Jim designed and I didn't like them much.

Sadly, as Hericalitus might have said if he had lived long enough,

Not quite a fat-headed as someone who could miss a reference to Roy

A group of us used to get togther from time to time to eat inexpensive
meals at a faux Chinese restaurant where they handed out fortune
cookies (that was a few years ago when they were not sealed in
plastic). They had lucky numbers and a "learn Chinese" bit on the back
that was a bit error-prone, but I digress.. I made up a very
authentic-looking fortune with Photoshop and a color laser printer and
snuck it into one physicist's cookie and made sure he got the special

nothing but misery". It had been a technically frustrating morning for
him.. and the somewhat delayed reaction was priceless. ;-)

Near Huntsville? You've got to be kidding ...

The University of Alabama at Huntsville (UAH) has a certain fame amongst
people who are persuaded by the evidence for anthropogenic global warming.
Two of the researchers there - Spencer and Christy - were a bit slow to
correct their satellite data for orbital decay, and for a while their
uncorrected figures deviated from the predictions of the climate models.

http://en.wikipedia.org/wiki/Satellite_temperature_measurements

Roy Spencer is a card-carrying fundamentalist, and John Christy has spent
time as a bi-vocatiinal mission-pastor. This may - in part - explain why
they are two of the nine top climate scientists (out of the top 300) who
aren't persuaded by the evidence for anthropogenic global warming. Maybe
they think a loving God couldn't be that mean.

http://www.sourcewatch.org/index.php?title=Roy_Spencer

http://www.sourcewatch.org/index.php?title=John_R._Christy

Their kind of expertise can't entirely be relied on

You seem to be rather desparate to get yet another AGW debate going,
aren't you? Forget it, since climategate nobody is interested much anymore.

BTW, it's not a university that matters, it's the employers that are
already in the area.

... And they are Baptists - perhaps not
as sincerely Baptist as the inhabitants of Urk are Calvinist, but still
pretty inflexible - so you'd run the risk of being rejected as a
schismatic Lutheran.

Baptists and Lutherans get along quite well, and I love their choirs.
They can make the rafters shake.

Unfortunately, that kind of belief can gnaw at the foundations as well as
shaking the rafters.

My faith is my foundation and it is unshakeable. Nothing you can do
about that

Right - it drifted away from the area where you can pose (tolerably
convincingly) as a state of the art expert, and you suddenly felt
flattery-deprived.

Joerg was making a point about moving into an even more rural area
than he occupies a the moment, and I made the point - made rather
better in "Freakonomics" - that high-tech is easier in big
conurbations. I throw in a joke about Alabama Baptists - playing on
the well-known fact that he is active in his local church - and get a
civilised response from him.

krw then poisons the thread with personal abuse - as is his habit -
and I gave him the Spenser and Christy response, which he deserved.

Then you jump in on krw's side. You may like his politics, but he's
got nothing else to recommend him, and you equally deservedly got the
same put-down.

What a sour ass you are. Maybe you were bashed too much as a child.

I wasn't bashed as a child. My parents did get married -
Congregationists do marry Methodists (not that my parents took the

have any resentments to take out on their kids. I didn't get on with
some of my age-mates and some were silly enough to try physical
violence, but I could give at least as good as I got, and nobody got
noticeably hurt or intimidated.

You resent it when your own attempts at bullying get acid responses.
Pity about that.

expecting the usual off-topic rant multiply ratio...

Think of it as enlarged opportunity for you to indulge yourself in
text-chopping and smart-ass one-liners. It's a pity that you aren't
much good at this kind of word-play, but you don't let that stop you.

The University of Alabama at Huntsville (UAH) has a certain fame amongst
people who are persuaded by the evidence for anthropogenic global warming.
Two of the researchers there - Spencer and Christy - were a bit slow to
correct their satellite data for orbital decay, and for a while their
uncorrected figures deviated from the predictions of the climate models.

Roy Spencer is a card-carrying fundamentalist, and John Christy has spent
time as a bi-vocatiinal mission-pastor. This may - in part - explain why
they are two of the nine top climate scientists (out of the top 300) who
aren't persuaded by the evidence for anthropogenic global warming. Maybe
they think a loving God couldn't be that mean.

Far from it. It was just a handy fact to drop on krw in reaction to
him calling me ignorant, which counts as gratuitous abuse in my book.

So why did you do it in response to my post? Not that I'd mind, just
curious.

Forget it, since climategate nobody is interested much anymore.

Climategate just illustrated that climate scientists get upset when
some denialist saboteur manages to smuggle a totally inadequate paper
into the peer-reviewed literature. When it turned out that the action
editor had ignored four peer reviews telling him that the paper was
crap, and the publisher refused to dump the - denialist - action
editor, most of the editorial board of the journal resinged in
protest.

The denialist lobby seized on the e-mails that covered the nuts and
bolts of the University of East Anglia finding out what had been done
and telling people about it, as if it was some sort of evil
conspiracy, when in fact it was just the peer-review mechanism in
error-correction mode.

It was just one more denialist campaign to persuade the general public
to distrust good scientific information which doesn't happen to suit
the financial interests of the fossil-carbon extraction industry. The
fact that you haven't realised that climategate was pure denialist
propaganda is a tribute to the effectiveness of the propaganda machine
- and a worrying indicator of the effectiveness of paid advertising in
moulding public opinion.

Read some of the more juicy emails again. Have you forgotten? Or purged
from your mind because it doesn't jibe with your mantra? It couldn't
have gotten any more damaging than that (for warmingists).

BTW, it's not a university that matters, it's the employers that are
already in the area.

And the potential employees that they've got to work with.

... And they are Baptists - perhaps not
as sincerely Baptist as the inhabitants of Urk are Calvinist, but still
pretty inflexible - so you'd run the risk of being rejected as a
schismatic Lutheran.
Baptists and Lutherans get along quite well, and I love their choirs.
They can make the rafters shake.
Unfortunately, that kind of belief can gnaw at the foundations as well as
shaking the rafters.
My faith is my foundation and it is unshakeable. Nothing you can do
about that

It's not your foundations that I'm worried about, it's the foundations
of the science that you - indirectly - rely on to make your money. If
your sub-contradtors were to reject experimental evidence because they
thought that the results didn't fit with their - say, anti-abortion -
theology you could eventually find yourself in serious trouble with
the FDA.

For the record, I am against abortion and if someone wanted me to work
on some device that is used in that area I will refuse. It is my right
to do so.

Abortion keeps the liberal population down ;-)

However I did decline participating in the new integrated circuit radio design
for the Claymore Mine. Opting instead to develop chips for the soldier's
