Ramp Type Oscillator with Bottom Release
In the past I did this (in bipolar), so that I got a near-zero release of the "dump" function by sensing saturation...
... easy with bipolar devices.
Any ideas on how to do it similarly with CMOS?
(Comparators sensing near zero are risky with CMOS due to crappy offset voltages.)
For the leftists in the crowd (too high a percentage ;-) this IS ON-TOPIC. ...Jim Thompson
