Internally compensated differential amplifier

摘要

The invention relates to a differential amplifier with internal compensation. The invention also relates to a regulator controller and a regulator which includes such an amplifier. The amplifier includes a preamplifier circuit and a gain circuit. The frequency response of the amplifier is based in part on internal compensation within the preamplifier circuit. The internal compensation of the differential amplifier includes a low frequency zero that is provided by the preamplifier circuit.
