Abstract
An amplifier may include a main signal path having a plurality of stages compensated by feedback elements, the plurality of stages comprising an output stage configured to receive electrical energy from a power supply and an auxiliary path independent of the main signal path and comprising an output stage compensation circuit configured to generate a compensation current proportional to noise present in the power supply and apply the compensation current to cancel a power supply-induced current present in at least one of the feedback elements.
