Abstract
Because of the nonlinearity of digital PWM generator and the effect of power supply noise in power stage, the error is introduced into digital class D power amplifier. A method used to eliminate the error is presented in this paper, and it is easy to implement. Based on this method, a digital class D power amplifier is designed and simulated, the simulation results indicate this method can basically eliminate the error produced by digital PWM generator and power stage, and improve the performance of the system.
