Abstract
Provided is a semiconductor device that is capable of performing background calibration during a reception operation without adversely affecting reception characteristics. During a reception operation, the semiconductor device detects a timing at which an invalid received signal occurs upon a gain change or a reception channel change and performs background calibration at the detected timing. In this instance, as the received signal is invalid, performing the calibration does not further decrease the substantial accuracy of reception. Moreover, an unnecessary signal component, which would arise when the background calibration is performed at fixed intervals, will not be generated as far as the background calibration is performed at random timing.
