Hello All,
I'm trying to determine if there is a way to make a voltage controlled resistor using an Op-Amp (or multiple op-amps). I want to use this VCR to control the gain of another op-amp but wanted to see if there was an altenative approach to using a JFETs or an LED/CDS photocell arrangement.
Thanks,
Jason O
