A class-D amplifier includes a switching transistor section, a filter, an analog to digital converter, and a feedback module. The switching transistor section is operably coupled to convert a serial input into a switched output signal. The filter is operably coupled to filter the switched output signal to produce an output of the class-D amplifier. The analog to digital converter is operably coupled to convert an analog input into a multi-bit digital signal based on a feedback signal, wherein the serial input corresponds to the multi-bit digital signal. The feedback module is operably coupled to the produce the feedback signal based on at least one varying property of the switching transistor section.
