Abstract

A system for a continuous time noise shaping analog-to-digital converter (“ADC”) with a suppressed carrier pulse width modulated (“PWM”) quantizer is disclosed. In particular, a suppressed carrier feedback signal may expand the dynamic range of a sigma delta modulated ADC and enhance the stability of the noise shaping loop.
