摘要： The invention provides a continuous-time delta sigma modulator. In one embodiment, the continuous-time delta sigma modulator comprises a series of integrators, a quantizer, and a loop delay compensation circuit. The integrators are coupled in series and generate an analog output signal according to an analog input signal. The quantizer quantizes the analog output signal according to a reference voltage to generate a digital output signal as the output of the continuous-time delta sigma modulator. The loop delay compensation circuit adjusts the reference voltage of the quantizer according to the digital output signal to compensate the continuous-time delta sigma modulator for a loop delay.
