摘要
A distortion mitigation quantizer circuit includes a pre-quantizer to generate a first quantized signal having L output signal levels from an input signal and a digital pulse-width-modulation (PWM) circuit to modulate the first quantized signal using M modulating carriers with PWM carrier frequency fp and according to an over sampling ratio (OSR) N in order to generate a second quantized signal. In this case, a number of the modulating carriers M is substantially equal to twice L/N.
