Simple Real-Time Digital PWM Implementation for class-D Amplifiers With Distortion-free Baseband

A real-time, digital algorithm for pulse width modulation (PWM) with distortion-free baseband is developed in this paper. The algorithm not only eliminates the intrinsic baseband distortion of digital PWM but also avoids the appearance of side-band components of the carrier in the baseband even for...
