    Abstract: An Analog-Digital Converter (ADC) is provided. The ADC includes a plurality of sigma-delta modulators, a plurality of decimators, a plurality of differentiators, and a plurality of XOR operators. The plurality of sigma-delta modulators respectively convert analog signals to digital pulses. The plurality of decimators respectively convert a first sampling rate of a corresponding digital pulse to a second sampling rate which is lower than the first sampling. The plurality of differentiators respectively differentiate signals converted at the second sampling rate to perform delta modulation. The plurality of XOR operators extract a signal component changing with respect to the delta-modulated signals. Therefore, the number of interface pins between a modem and an RFIC can be reduced.
