Abstract
An amplification system, circuit, and method of performing offset cancellation are described. The disclosed amplification system is described as including a main amplifier circuit that receives an input signal and produces an output signal, a two-phase output sampler, and an offset correction circuit. The two-phase output sample samples the output signal of the main amplifier circuit in two different clock domains and determines a delta between the samples. The delta is used to assist the offset correction circuit in generating an offset correction feedback for the main amplifier circuit.
