Abstract
A duty cycle correction circuit employing a sample and hold charge pumping method is disclosed. The duty cycle correction circuit includes a duty regulator which generates an output signal by regulating duty of an input signal in response to a regulation voltage, and a charge pump which generates the regulation voltage by inputting the output signal, wherein ripple of the regulation voltage is reduced by sampling the regulation voltage in a predetermined time interval.
