Abstract

Class D audio amplifiers are used in the audio devices. Nowadays, they are preferred due to their high power efficiency compared to the other classes such as: class A, B and AB. In this paper, a class D audio amplifier is designed. It uses MOSFETs in switching mode, a closed-loop with second order integrator, pulse width modulator and low pass filter. The system is simulated with Orcad-PSpice software. Simulated results show good values of THD+N, SNR, PSRR and Efficiency.
