The operational amplifier, or op amp, is one of the most basic building blocks used in analog circuits. Ever since single-chip op amps were introduced in the 1960s, thousands of different types ...
The auto-zero amplifier uses a chopper amplifier and an op-amp just as the chopper-stabilised amplifier does, except the chopper does not contribute directly to the output. Instead it forms a pair ...
