Abstract
The present invention provides a delta-sigma ADC, wherein the delta-sigma ADC includes an adder, a loop filter, a quantizer, a DAC and a reference voltage compensator. The adder is configured to subtract a feedback signal from an input signal to generate a first signal. The loop filter is configured to receive the first signal to generate at least one filtered signal. The quantizer is configured to generate a digital output signal according to the at least one filtered signal. The DAC is configured to perform a digital-to-analog conversion operation on the digital output signal to generate the feedback signal. The reference voltage compensator is configured to compensate a reference voltage to generate an adjusted reference voltage according to the digital output signal, wherein the adjusted reference voltage is used by the DAC to perform the digital-to-analog conversion operation on the digital output signal to generate the feedback signal.
