Abstract:
A duty cycle corrector includes a duty adjusting unit configured to adjust a duty cycle of an input clock in response to a duty correction code and generate an output clock, a duty detecting unit configured to measure a difference between a high pulse width and a low pulse width of the output clock and output a difference value, and an accumulating unit configured to accumulate the difference value to generate the duty correction code.
