  • Patent number: 7535274
    Abstract: A delay control circuit includes a first delay unit, a signal regulation unit, a selector and a second delay unit. The first delay unit is used for delaying an input signal and generates a delayed input signal. The signal regulation unit is coupled to the first delay unit and outputs a rising edge delay signal and a falling edge delay signal according to the input signal and the delayed input signal. The selector is coupled with the signal regulation unit and outputs one of rising edge delay signal and falling edge delay signal according to the control signal. The second delay unit is coupled to the selector for delaying the output of the selector and outputting an output signal.
