A Sigma-Delta (&#x3a3;-&#x394;) analog-to-digital converter (ADC) and operation method thereof are provided. The &#x3a3;-&#x394; ADC includes a &#x3a3;-&#x394; modulator, a dynamic element matching (DEM) circuit and a control circuit. An input terminal of the &#x3a3;-&#x394; modulator is configured to receive an analog signal. The &#x3a3;-&#x394; modulator is configured to convert the analog signal into a digital signal based on a feedback signal. The DEM circuit is coupled to the &#x3a3;-&#x394; modulator to receive the digital signal. The DEM circuit is configured to perform a DEM algorithm on the digital signal to generate a feedback signal, and provide the feedback signal to the &#x3a3;-&#x394; modulator. The control circuit listens to the digital signal to detect a mute period. The control circuit disables the DEM circuit during the mute period to suspend a progress of the DEM algorithm.
