Abstract

See full text

A sigma delta (SD) pulse-width modulation (PWM) loop includes a loop filter implementing a linear transfer function to generate a loop filter signal, wherein the loop filter is configured to receive an input signal and a first feedback signal and generate the loop filter signal based on the input signal, the first feedback signal, and the linear transfer function; and a hysteresis comparator coupled to an output of the loop filter, the hysteresis comparator configured to receive the loop filter signal and generate a sigma delta PWM signal based on the loop filter signal, wherein the first feedback signal is derived from the sigma delta PWM signal.
