Abstract
The object of this invention is to provide a timing circuit that can change a clock period with low power consumption. The timing circuit includes a clock generator, comparatorsandfor comparing an inputted control voltage TDV and reference voltages VR, respectively, retaining circuitsandfor retaining outputs of the comparators, respectively, and circuitsandfor producing timing pulses TDT as an output thereof based on outputs of the retaining circuits and clock signals outputted from the clock generator. Each comparator receives a first clock signal SS outputted from the clock generator and is operated only for a time corresponding to a short pulse width of the first clock signal SS.
