Yes, Jim, I think I sent that to you back in the day. But, you have
to be careful. It really does what is in effect an inverse FFT of the
Sparams, so it doesn't include any of the really important data you
need to do a good spice simulation when you are concerned more with
transient response.
That's exactly the point, especially with LDMOS. When a big old fat one goes phut ... *KABLAM* it's mucho Dolares down the drain. Not the best way to make friends at a new client.


... IBIS models are a 'little' better, but they are
also very behavioral and I was always interested in the little
'gotchas' that following them too closely led to.

Joerg, You have way too much "phut ... *KABLAM*" in your life! What
is it you're doing to cause all that ?:-)

Crikey! Here I am months from the big '70, and I can count all my
"phut ... *KABLAM*"'s on one hand... and they were ALL in the lab, NOT
in the field, just great entertainment for my technicians... nothing
quite like the boss getting knocked off his lab stool to amuse the
troops ;-)
Mine are also in the lab. It usually happens when we try to push the envelope a bit too much, when models don't jibe or when something else breaks down and causes a huge reflection or things like that. I do a lot of heavy duty pulse stuff where this is a normal part of life.

You are doing IC design. That's like signal corp versus a job in the artillery.
What a pile of horse pucky. Who do you think did Hubble magnetic
support, a satellite spinner for objects as big as a car, and
automotive environment for years and years and years ?:-)

Then why does the electronics in cars croak so often ... ?

<duck and run>
Only GM (Government Motors) and Mercedes, judging from local
observation ;-) ...

Wasn't it Ford who managed to place an ingnition controller hybrid or something similar on top of the engine?

Yep, it was called a "carburetor". ;-)

I thought that was a rather stupid thing to do. Probably the cause of issues like "doesn't start when still warm".

That's the one.

The electrical failures in my Chrysler weren't truly electrical. They had mounted the alternator on an aluminum strut. Now that was really stupid.

Chrysler's body didn't last long enough for the electronics to be
stressed.


There you've got a point. Mine had the right rear suspension coil pop into the cabin after about 6 years. Pathetic. Never bought a Chrysler again.


... As you may properly deduce from my postings here, I
am of the big hammer school... if I can't kill it with a big hammer,
get a bigger one. I don't tolerate pansy designers.

As a consultant, I just politely decline when I realize that the rest of the team ain't up to snuff. After all, that carries some liability risks with it.

Consult for the government. No worries at all.


My work comes mostly via word-of-mouth, very little government connections except with one new client.
