Abstract
An amplifier system in accordance with an aspect of the present invention comprises a switching amplifier that drives a load with a pulse-width modulated (PWM) output signal that varies between first and second rails based on a first control input signal, and a common mode supply that provides a switching signal that varies between third and fourth rails to maintain a common mode voltage of the load at a level that is between the first and second rails.
