Suggested by Fairchild in a 1980s publication, this multiplier uses operational amplifiers from that time. The power supply must be symmetrical.
This circuit was found in the November 1992 issue of Radio Electronics magazine. The circuit has...
This simulation shows how to use an operational amplifier as a voltage comparator. The sample uses the...
