Abstract
Sample and hold circuits are used to detect a DC component of an AC signal on an amplifier's output to generate a feedback signal that is applied to the amplifier's input to cancel out a DC component of an AC input signal. The sample and hold circuits detect the peak excursions of the AC output signal and apply the stored peaks to averaging circuitry which determines the magnitude of the DC component of the output signal.
