摘要：
A duty cycle corrector includes a delay unit configured to adjust an input clock and an inverted input clock with a delay value controlled in response to one or more control signals and to generate a positive clock and a negative clock, and a duty detector configured to receive the positive clock and the negative clock, to detect duty ratios of the positive clock and the negative clock and to generate the one or more control signals.
