Abstract: In a synchronous delay circuit including a first delay circuit array which is constituted of a plurality of cascade-connected delay circuit stages, and a second delay circuit array which is constituted of a plurality of cascade-connected delay circuit stages arranged to have a signal propagating direction opposite to that of the first delay circuit array. Each of the delay circuit stages of the first and second delay circuit arrays includes a CMOS inverter receiving an input signal. A P-channel MOS transistor of the CMOS inverter, a switching P-channel MOS transistor and an additional resistor are connected in series between a power supply line and an output node of the delay circuit stage. An N-channel MOS transistor of the CMOS inverter, a switching N-channel MOS transistor and another additional resistor are connected in series between the ground and the output node of the delay circuit stage. Thus, the current drive capability of each unitary delay circuit is decreased by the additional resistors, so that the delay time per one unitary delay circuit can be increased while minimizing the increase of the jitter. Accordingly, the area of the delay circuit arrays required to obtain a desired delay time can be reduced.
