Abstract
A first circuit is disposed on the semiconductor substrate, operates synchronously with a first clock signal, and outputs a first output signal delayed by a first delay time from the first clock signal. A first measuring circuit measures indirectly a first increase and a first decrease of the first delay time. A setting circuit operates synchronously with the first clock signal, outputs a second clock signal delayed from the first clock signal by a second delay time adding the first increase and subtracting the first decrease. A second circuit inputs the first output signal and operates synchronously with the second clock signal.
