We get Electronic Design at work and the first thing I turn to is Bob's articles in the back.
I was fortunate enough to buy from himself directly a book for my stepdaughter. He wrote a book "How to drive into accidents - and how not to". He signed it too.
Sometimes I would e-mail Bob if I saw a peculiar problem and we'd banter it around. Had some occasional troublesome transistors and after talking via email he said I could mail them to him when I came across some of the odd ones (2n3904s).
My most recent e-mail to him was last week about why as a unity gain buffer an LMC6034 will oscillate under a capacitive load but an LM324 would not oscillate in the same circuit. He explained it to me very clearly! The older LM324 isn't as internally compensated as the modern CMOS LMC6034 is.
It's the internal compensation which is causing the oscillation.
We had quite a discussion about why some of us love to persist with vacuum tubes in a solid state age too!
Very sad indeed, both Jim Williams and Bob Pease gone way too early.
National has a video up to remember him.
