Abstract
A clock distributing circuit, that comprises a clock distribution output circuit for inputting an external clock, outputting a first clock that synchronizes with the external clock, and distributing the first clock to each of load circuits, and a distributed clock input circuit disposed on input stages of all or part of the load circuits and adapted for inputting the first clock and outputting a second clock that synchronizes with the input clock, wherein one of the clock distribution output circuit and the distributed clock input circuit includes a phase difference-voltage converting circuit for converting the phase difference between the input clock and the output clock into a voltage, and a voltage control type delay circuit for delaying the input clock corresponding to an output voltage of the phase difference-voltage converting circuit and for outputting the delayed input clock.
