A delay-type phase adjusting circuit including a first variable delay circuit for receiving a reference clock signal and adding a delay to the reference clock signal, for output a phase comparator for receiving an output of the first variable delay circuit and the reference clock signal and detecting a phase difference therebetween a control circuit for generating a control signal for variably controlling a delay value of the first variable delay circuit based on a result of phase comparison by said phase comparator a second variable delay circuit for receiving an input signal and adding a delay to the input signal, for output a computation circuit for receiving a predetermined value and the control signal and variably controlling a delay value of the second variable delay circuit. |
