A Delta-Sigma analog-to-digital converter and a method thereof are provided. According to a non-overlapping clock signal, the Delta-Sigma analog-to-digital converter performs an integration process on the difference between a plurality of input signals and the corresponding feedback signals to generate an integrated signal. Then, according to a selecting signal, the integrated signal is selectively output. Afterward, according to a latch signal, the selectively output integrated signal is quantized and latched by only one quantizer, thereby generating a digital output signal correspondingly. Accordingly, by using only one quantizer, the present invention can have the same function as the prior art which uses a plurality of quantizers, thereby decreasing the occupied chip area.
