just such a system together, and didn't have much trouble getting 0.1% accu racy.
uency converters - presumably for the slow A/D converter market - which sta y highly linear even at very low oscillation rates, which is nice when you have to cope with a large dynamic range.
second transistor inverted for minimum off-set voltage - slow as a wet wee k, but adequate for industrial control. Somebody else's idea, and I got stu ck with showing that it worked.
Not at all. I thought that it was a cute idea at the time, and was happy to have the job of reducing it to practice - which wasn't trivial. My boss's first approach didn't work at all well - too much difference in the propaga tion delay between the - different - switches he'd had in mind. Using the s ame switches in both halves of teh circuit - V-to-F and PWD - made it work quite a bit better.
In general I'm always happier to use an idea that has been shown to work th at one that somebody has dreamed up (even when that somebody is me). Less c hance of inconvenient surprises.
