Abstract

A class D audio power amplifier is presented. It is composed with full-bridge structure and a closed-loop pulse width modulation. It achieves a maxim efficiency of 94% when output power is 3W. When sine wave input signal frequency is 1KHz and output power is 3W, the THD of output signal is 0.1%.
