摘要： According to one embodiment, an analogue to digital converter converts an analogue input signal to a digital output signal. The converter includes an analogue to digital converting unit, a multiplexer, a pseudo-alias signal generator, a gain controller, and an alias signal compensator. The analogue to digital converting unit converts the analogue input signal to a plurality of digital signals. The multiplexer sequentially selects one of the digital signals and outputs the selected digital signal as a multiplexer output. The pseudo-alias signal generator generates a plurality of pseudo-alias signals from the digital signals. The pseudo-alias signal simulates an alias signal component in the multiplexer output. The gain controller generates a plurality of gain control signals by using the pseudo-alias signals. The gain control signal controls gain of the digital output signal. The alias signal compensator compensates the alias signal component by using the gain control signals.
