Abstract

A differential input amplifier stage having improved frequency compensation. Frequency compensation is achieved by cancelling one-half of the signal output of a differential error amplifier in the input stage, such that all error signals must pass through a "current-mirror" type load circuit in which a resistor-capacitor network is provided to roll off gain of the input stage.
