Original Abstract Submitted
A switching-amplifier circuit for computer systems generates a buffered version of a received input signal. Power supply circuits coupled to the switching-amplifier circuit adjust driver power supply and driver ground supply voltage levels over respective continuous ranges of voltages based on a magnitude of the buffered signal. An output stage included in the switching-amplifier circuit generates an amplified version of the received input signal that includes a series of pulses that transition between the respective voltage ranges of the driver power supply and driver ground supply, where the respective widths or frequencies of the series of pulses encode a magnitude of the amplified version of the received input signal.
