Abstract
A circuit for correcting a duty-cycle comprises a duty-cycle adjuster for changing a duty-rate of an input clock signal according to a duty control signal; a duty-cycle detector for detecting a duty-rate of an output clock signal based on the input clock signal and the output clock signal from the duty-cycle adjuster; and an algorithm-based digital controller for performing an algorithm according to a duty-rate detection signal outputted from the duty-cycle detector to generate the duty control signal.
