摘要:
A duty cycle correction circuit includes a duty cycle correction portion that is configured to output a correction signal that is obtained by correcting a duty cycle of an input signal and to output a delayed signal that is obtained by delaying the correction signal, a complementary portion that is configured to output a complementary signal that is the complement of the delayed signal, and a phase interpolator that is configured to phase interpolate the complementary signal and the correction signal.
