Abstract
An amplifier apparatus includes: (a) an integrator having an input for receiving an input signal, and integrating the input signal to present an integrated signal; (b) a first comparer coupled with the integrator for comparing the integrated signal with a varying reference signal to produce an output signal; and (c) a feedback circuit, coupled to receive the integrated signal and coupled with the input structure, that includes: (1) a second comparer coupled for receiving the integrated signal and comparing the integrated signal with a reference level related to the reference signal; the second comparer presents an actuating signal when the integrated signal has a predetermined relationship with the reference level; and (2) a switch coupled with the second comparer unit and with the input and responding to the actuating signal to affect the input signal appropriately to reduce the integrated signal when the actuating signal is at a predetermined level.
