ABSTRACT:
A delay circuit delays an input signal having a predetermined frequency by a time corresponding to a control signal. A delay amount detector detects a signal delay amount of the delay circuit. A charge pump circuit generates a DC voltage corresponding to a pulse width ratio between the input signal and a detection signal of the delay amount detector. This DC voltage is fed back to the delay circuit as a control signal.
