0.5*L*I^2 = Qg*Vg (Qg = Total Gate Charge, from data sheet, at
gate voltage, Vg)

[neglecting losses in diode and resistor, I'll include that RSN,
otherwise someone will have another hissy fit :]

Not "L = R^2 * C"

"Close to it" (pretty close actually) would be...

0.5*L*I^2 = 0.5*C*V^2

It's all about energy transfer from magnetic storage to capacitive
storage... and boost converters rely on it.

I have a problem with Jim's pages, the lines are to thin to see,
I suspect my reader, and will try adobe. How do I pull up associations?
I've done it a dozen times but can't figure it out now.
The reader I use is Foxit (I think, I find no identifying info)


Right click on the file and choose: 'Open With', then select 'Choose
Program'. It will tell you what the default program is, and let you
change it.


Thanks, I had to save it before I could right click.
I looks much better using Adobe than it does Foxit Reader.
Anyone else have a problem seeing the lines...
hmm, now after saving the file and opening it with Foxit,
the schematic looks better with Foxit than Adobe.
Any time I want to view Jim's schematics, I'll save it first.
I think that was the solution.

Thank You! I had the same problem. After reading your
post, I saved it then opened it. Bingo! Now it's

...Jim Thompson
It better be incorporated, "Inc" stands for "incorporated"; anything
else would be false advertizing and subject to State investigational
consequences (which is decidedly NOT-linear and NOT computational).

Look it up at AZ Corporation Commission

items I think were bought only because they were on sale, but over all,
I know she has saved 10s of thousands of dollars.

Ya, my usual cutting spot is sticking out the door of my shed, the floor
is 12" to 14" of the ground so it gives some clearance. But I'm looking
forward to the Jawhorse holding my piece firm and by up where I'm standing.

Skil Model 77 perhaps? Fix or rebuild it, don't replace it. I've
fixed about five of them. They're quite easy.

There should not be much vibration. On which axis does it vibrate?
Blade or motor? My guess(tm) is:
1. The motor armature shaft is slightly bent causing the vibration,
2. The armature wasn't properly balanced.
3. Defective bearing(s) at the motor end of the armature.
4. The threaded connection between the armature and the worm gear
might be loose and wobbling.

May as well also replace the electrical parts, which tend to wear or
break:
<http://store.eurtonelectric.com/skilwormdrivesawrebuildkit77-kit1994.aspx>
If you're going to be doing a rebuild, there are plenty of other parts
that can be commonly found and easily replaced.
<http://www.ereplacementparts.com/skil-hd77-type-worm-drive-saw-parts-parts-c-130_160_1005.html>
Be sure to identify the exact model as there are several variations.

Just curious. How often has simulation revealed something, you didn't
already know, or suspect?

Not very often. Occasionally it reveals a latch-up/lock-up I didn't
anticipate. And virtually _all_ CMOS OpAmps require simulation to get
the loopgain compensation correct... the Level=3 school boy equations
(the only ones hand-tractable) don't even do a good job at gain
prediction.


Reason for my question, when I first started Engineering, my mentor looked
over my shoulder at my several pages of equations and laughed
uproariously. He said, you'll get lost in all those equations. Instead use
these simple models, then when you know what you have, verify with those
lengthy equations. He was right. Thus today, rarely, if ever, does the
simulation do anything but verify.


Yep. That's what I've attempted to convey... design with your head,
then verify via simulation.

The neon bulb modeling exercise was just to prove to myself that I
could create a model for a very abrupt slope change while maintaining
finite derivatives. Otherwise I have no use for a neon bulb...
haven't used one in a circuit for probably 50 years.

Pretty good weaseling, a B+ at least.

In his case? Every project. He designs bugs in and simulates them out. Most

uproariously. He said, you'll get lost in all those equations. Instead use
these simple models, then when you know what you have, verify with those
lengthy equations. He was right. Thus today, rarely, if ever, does the
simulation do anything but verify.


Good point. Jim says he has a 20,000 transistor analog CMOS circuit. It has to
be low standby power, so he's trying to figure out how to use Spice to find
floating nodes.

Why didn't he design it to not have floating nodes? Does he not understand his
own design?

Or someone else designed it, in which case he still doesn't understand it.

Analysis, either mathematical or using a simulator, is a poor replacement for
design and understanding.

I'm a big fan of belt-and-suspenders, though, especially if it doesn't
take any extra effort. Using gmin and split supplies, plus some simple
script to parse the .op or .raw file, could be quite a good use of time.

Nobody's going to place and wire 20000 transistors by hand, so there has
to be some combination of manual and automatic generation. Even using
the greatest care, you could have some bug in your design software,
misnamed nodes or something, and an automated way of finding that with
zero effort would be pretty useful.

Place, yes, wire, no... wiring is usually automated (that's part of
what LVS is all about... the netlist describes the connection), then
the layout engineer rubber-bands and re-routes to suit.

Besides the whole 20,000 aren't done at once. I/C layout is by
convention (and ease) done cell-by-cell. These days it is also common
to have at least three metal (wiring) layers, or more.

Misnamed nodes isn't an issue (unless forced, node naming is
automatic). Identifying those that can go wandering off is.

Hopefully I'll find a way to do this without splitting the supplies
(necessary if you use the gmin approach). Splitting the supplies make
me nervous because I keep running into modeling types that want to
call the substrate node 0 (zero), when it should be...

?SUB|[@SUB]|~SUB|0|

which assigns substrate connection to node 0, _only_ if the substrate
node isn't specifically declared.

Searching thru my symbol library to make sure I got that script
correct I noticed that, in PSpice, I have 846 personalized symbols :-[

I love to cook with wine. Sometimes I even put it in the food.
