Abstract
A delay locked loop circuit includes a delay replica model unit for reflecting a delay time of an actual output path to a source clock and outputting the reflected source clock as a delay replica clock, a detector for detecting a remaining time after subtracting a time corresponding to a multiple of a clock cycle of the source clock from a time corresponding to a phase difference between the delay replica clock and the source clock, and a delay locking unit for delaying the source clock for a delay time to synchronize a clock generated by delaying the source clock for the detected remaining time of the detector with a phase of the source clock.
