The operational amplifier is arguably the most useful single device in analog electronic circuitry. When you apply them in the circuits, you must know their basics and functions. As for the function ...

Operational amplifiers (op amps) have proliferated from specialized instruments made from large tubes to tiny monolithic circuits composed of a sliver of silicon, germanium or gallium arsenide. Dozens ...

The very basics of operational amplifiers. Learn comparator, inverting, and non-inverting op-amp configurations. An operational amplifier, or op amp, is a dc-coupled high-gain electronic voltage ...
