    I never interviewed a Georgia Tech grad, but Marshall Leach, Jr.
    certain has the credentials.

    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.

    Yep. CK722, CK760, CK761 plus a number of the GE vacuum "pinch" tube
    sealed devices.

    I'll give them to my kids before the tax man tries to "death tax"
    them.

    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 ;-)
    I don't know any of those.
    Yep :-(

    Bingo! That's exactly where one of my clients finally got they analog
    guy from. Now he has to get used to the fact that there is no more ice
    skating because it's Southern California.
    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.

    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.

    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.

    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.

    Yorktown Heights is "upstate" ?:)

    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.

    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.

    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.

    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.

    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!

    By comparison to 590 Madison avenue, it is.

    Fiche is NOT on nitrate film! That comes from the silent movie days or
    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
    film REALLY burns fast!) Me and a buddy once set a reel on fire in his
    driveway just for fun. Made an amazing fire!

    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.

    Nitrocellulose == guncotton.

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

    Cheers!
