But there has got to be an alma mater that sticks out. Or maybe a

I've interviewed plenty of UC Berkeley grads, and you could find an
analog designer there.This doesn't mean every grad from UCB will know
analog. The worse Ivy League has got to be hands down MIT. I assume it
was a good university at one time given it's reputation. But I
interviewed undergrads that didn't know basic s-plane stability
issues, as if they don't teach classic control theory anymore What
little analog they knew was bipolar.

A real surprise are the University of Toronto grads. These guys know
analog and signal processing.

The trouble with low power (assuming you mean micropower) is you
really need to be a careful designer, especially if the chip is
designed to have low quiescent power but handle high current. You also
need the benefit of seeing a few designs that didn't work, hopefully
not your own but from the company portfolio of goofs. One of the
classic bugs is designing micropower bandgaps, only to have them get
pumped from an on-board switcher. You have to throw in all sorts of
parasitics to make sure nothing sneaks into your reference.

Do you still have some of the first transistors?

Took non-linear control systems in grad school. Instructor scared the

It takes experience. But most importantly it requires to say good-bye to
the temptation to use chips in the can or digital processing for
everything that looks complicated. It's often back to transistors and
you've got to know those things inside out.

Maybe that's why there are no (cheap) ultralow brethren to the TLV431.
If you want less than 10uA cathode current on the board level it either
becomes very expensive, very large or you can forget about a reference.

IBM used to be headquartered in Manhattan. Then they decided that

The Intersil references are amazing. They're a floating-capacitor
EEPROM sort of cell connected to a fA follower opamp. They charge them
up to the right voltage at the factory, then ship them. They are very
stable and low noise for micro bits of power.

For us board level guys the situation looks pretty dire.

You can do a MOSIS run on old processes for a few $k. One day you should
put all of the little circuits you have always wanted but can't buy onto
one little chip, the "Joerg special". Design it into one of your products,
making sure that you hook up all of the pins, and manufacture it in the
shadiest overseas contract manufacturer that you can find. Pretty soon
there will be exact copies coming out of 15 different fabs and we'll have
an eternal supply.

But it's already there. Guys like Jim have tons of designs ready to go.
All it would take is getting it into the market. AFAICT something like a
1uA cathode current version of a common ref chip would really take off
in the marketplace, provided it's less than 10c in qties. It doesn't
even need to be adjustable of have a large compliance range.

analog designer there.This doesn't mean every grad from UCB will know
analog. The worse Ivy League has got to be hands down MIT. I assume it
was a good university at one time given it's reputation. But I
interviewed undergrads that didn't know basic s-plane stability
issues, as if they don't teach classic control theory anymore What
little analog they knew was bipolar.

Probably only the duds applied to your company ;-)

However I never had control systems, per se, undergrad... just a very
good math background to understand it if I needed it. (and that was
more than 45 years ago.)

Took non-linear control systems in grad school. Instructor scared the
piss out of me by announcing that, to weed down the class size, he was
giving an exam in undergrad control systems... pass or walk :-(

I got the best score, and "A" as my final grade ;-)

A real surprise are the University of Toronto grads. These guys know
analog and signal processing.

I don't know any of those.

The trouble with low power (assuming you mean micropower) is you
really need to be a careful designer, especially if the chip is
designed to have low quiescent power but handle high current. You also
need the benefit of seeing a few designs that didn't work, hopefully
not your own but from the company portfolio of goofs. One of the
classic bugs is designing micropower bandgaps, only to have them get
pumped from an on-board switcher. You have to throw in all sorts of
parasitics to make sure nothing sneaks into your reference.

Yep :-(

Maybe that's why there are no (cheap) ultralow brethren to the TLV431.
If you want less than 10uA cathode current on the board level it either
becomes very expensive, very large or you can forget about a reference.

Hardly a week goes by that I don't design a micro-power BandGap into a
chip ;-)

Dang, I just knew you'd say that ...

For us board level guys the situation looks pretty dire.

You can do a MOSIS run on old processes for a few $k. One day you should
put all of the little circuits you have always wanted but can't buy onto
one little chip, the "Joerg special". Design it into one of your products,
making sure that you hook up all of the pins, and manufacture it in the
shadiest overseas contract manufacturer that you can find. Pretty soon
there will be exact copies coming out of 15 different fabs and we'll have
an eternal supply.

But it's already there. Guys like Jim have tons of designs ready to go.
All it would take is getting it into the market. AFAICT something like a
1uA cathode current version of a common ref chip would really take off
in the marketplace, provided it's less than 10c in qties. It doesn't
even need to be adjustable of have a large compliance range.

The 10c part is the problem - the stock market analysts probably won't
knowingly let a semiconductor company embark on a new product with less
that 50% gross margin, and that sounds hard for 10c, tested etc. Anyway
their marketing guys would get some big ideas and try to sell it for $1.50
then cancel it a couple of years later because nobody bought it. On the
other hand, maybe there is a Chinese semi mfg who would be happy to accept
a bit less margin.

The Intersil references are amazing. They're a floating-capacitor
EEPROM sort of cell connected to a fA follower opamp. They charge them
up to the right voltage at the factory, then ship them. They are very
stable and low noise for micro bits of power.

John

It's must be much less than fA.

One day I want to get two of them and get one of them X-rayed a few times,
to see if that affects the voltage. I guess it can't be too bad or they
wouldn't be able to use them in anything that you would take to the
airport.

Poughkeepsie? That's where my father had to go, looong flights back in

It would definitely be too cold up there for my wife. Her ideal place
would be where winter simply doesn't happen. Like Hawaii, but there is
no work for me and getting to clients would take forever.

Nah, the Watson Lab in Yorktown Heights. Best sandbox in the world at
one point, still very very good (and improving since the low point in
about 2000).

IBM used to be headquartered in Manhattan. Then they decided that
Manhattan might be nuked by the Soviets, and it would be in the
interest of the USA that IBM survive, so they moved upstate.

John

Yorktown Heights is "upstate" ?

...Jim Thompson

Armonk. They were probably thinking of getting out of a-bomb range,
not h-bomb range.

IBM has an interesting history. Read "The Maverick and his Machine",
by Maney, about Watson Sr. Another interesting book, almost all
technical, is "IBM's Early Computers" by Bashe et al... some very
weird architectures!

shortly thereafter. Long before fiche was invented. Projecting a movie
in the old days was a major thrill. If the film stuck in the projector
gate the high intensity lamp set fire to it which traveled up the film
to the upper reel which thence set the whole place on fire! (nitrate

Once upon a time a school called Harvey Mudd did this well. Maybe
they are still at it.
I would consider U-Cal and Cal-State unlikely producers of even solid
based trainables. The real resume as opposed to the normally
prescribed one for getting through HR can really count. There are
still a few non-degreed engineers as well.

In Jr. High or so, I had a buddy who made some. It does burn real good!
