Abstract

The present disclosure introduces a simple method and apparatus for a Class-D amplification and Pulse Width Modulation (PWM) of an input signal, such as a voice signal. The proposed circuits do not require reference input signals such as triangular signals; rather, the combination of the circuits' self-oscillating device arrangements and the delay elements performs pulse width modulation at higher frequencies while producing less noise. Among other advantages, these circuits offer shorter response time, less distortion, better power supply ripple rejection, larger negative feedback, and simpler construction. The recommended Class-D amplifiers can be used with speakers and can have single-ended or differential input.
