The advancement of power MOSFET fabrication technology has aided the reduction of power stage errors in class-D amplifiers (amps). This reduction reveals intrinsic distortion, which is a key performance limiter in modern pulsewidth-modulation (PWM)-based class-D amps. In this brief, a dual-feedforwa...
