Abstract: A quantizer of a sigma-delta modulator includes a pulse width modulator (PWM), a converter and a voltage level tracing device. The PWM receives an input signal, and generates a PWM signal according to one or more sawtooth waves and one or more reference voltages. The converter is connected to the output of the PWM and digitizes the PWM signal to generate an output digital value. The voltage level tracing device is connected to the output of the converter, and receives the output digital value to generate a reference voltage adjustment value. The reference voltage adjustment value is transmitted to the PWM for adjusting the reference voltage, so as to change the next corresponding voltage level of the sawtooth wave to track the input signal.
