Abstract
This paper presents a feed-forward power-supply noise cancellation technique to achieve high power-supply rejection ratio (PSRR) in single-ended class-D audio amplifiers. To show the effectiveness of the technique, it is implemented on a first-order single-ended pulse-width modulation (PWM) class-D amplifier. The implemented technique improves the PSRR from 20 Hz to 20 kHz independently of the close-loop compensator's filter-order. The design...
