What I’d stumbled upon was a chopper amplifier, a slightly ungainly and long superseded solution to the problem of DC amplification from the days before ubiquitous integrated circuit op-amps.

An operational amplifier, or op-amp, is basically a differential amplifier, i.e. it is used for amplifying the difference between two inputs. There are two signal input terminals and one signal output ...

This is not always the case with all types of amplifiers. It may be desirable to have the transistor conducting for only a portion of the input signal The portion of the input for which there is an ...
