We describe the design of a micropower digital pulsewidth modulator (PWM) for a hearing instrument Class D amplifier. The PWM embodies a novel delta-compensation (έC) sampling process and a novel pulse generator. The C process is sampled at the same low rate as reported algorithmic sampling processe...
