Abstract:
A class DH amplifier is provided. The amplifier is generally comprised of a tracking power supply, a class D amplifier section, and a carrier generator. The tracking power supply receives a supply voltage and an analog input signal, and the tracking power supply provides an input for the carrier generator. Based on its input from the tracking power supply, the carrier generator can output a positive ramp signal and a negative ramp signal to the class D amplifier section. The class D amplifier section can generate an output signal base on the analog input signal and the ramp signals from the carrier generator.
