ASK RECEIVER AND IC CHIP INCLUDING THE SAME

PROBLEM TO BE SOLVED: To correctly demodulate an ASK signal while reducing deterioration in receiver sensitivity for each individual in an environment in which a DC offset and noise of an amplifier are changed by variations in individual and environment.SOLUTION: An ASK receiver includes an automatic offset adjustment unit 13 for performing automatic adjustment of a DC offset given to between difference inputs of an amplifier 11 for amplifying an ASK signal, and an offset adjustment enable signal generation circuit 14 for controlling timing of the automatic adjustment so that the automatic adjustment is performed at a predetermined interval.
