摘要
A delta-sigma modulator includes a receiving circuit, a loop filter, a quantizer with a negative capacitor circuit and a feedback circuit. The receiving circuit is arranged for receiving an input signal and a feedback signal to generate a first signal. The loop filter is coupled to the receiving circuit, and is arranged for receiving the first signal to generate a filtered signal. The quantizer is coupled to the loop filter, and is arranged for generating a digital output signal according to the filtered signal, wherein the negative capacitor circuit is arranged at an input terminal of the quantizer. The feedback circuit is arranged for receiving the digital output signal to generate the feedback signal.
