Abstract
According to the one embodiment, a semiconductor circuit includes: an analog-to-digital conversion circuit including a first analog-to-digital converter configured to sample at least one first sampling signal regarding an input signal based on a first clock, and a second analog-to-digital converter configured to sample at least one second sampling signal regarding the input signal based on a second clock shifted from the first clock by a first time; and a first calibration circuit configured to calibrate at least one timing of the first clock and the second clock based on a calculation result of a moving average of the first sampling signal and the second sampling signal.
