Abstract

A modulator including a delta-sigma modulation circuit having an order greater than 1, and configured to modulate an input signal into a Pulse Density Modulated (PDM) signal; and a Pad Asymmetric Compensation (PAC) circuit configured to linearize a relation between a magnitude of the input signal and a number of rise or fall transitions of the PDM signal by maximizing the number of rise or fall transitions of the PDM signal, and to output a modified PDM signal, wherein the linearized relation is for compensating for any offset in the PDM signal.
