Hi, all, trying to build a precision rectifier with no good results.
I only get VEE (about -9V) on the output pin 6 and nearly the same on input pin 3. Disconnecting the DC filter from the output, and trying with and without the 100K load resistor, still shows no rectified pulses at the output. I tried without the 100K input load, too, and various values of load (DC return) resistors, and feedback resistors too. I also tried without the buffer. Nothing I did actually makes this work. I tried with an LM741 as well, feeding 1KHz at 150mV P-P sine...same behavior. Disconnected the power supply filters and that didn't help.
What am I missing? Thanks...
