Abstract
A circuit configured to correct a duty cycle includes a clock dividing unit configured to delay an input clock signal by a specified delay amount and to generate a plurality of delayed clock signals, a clock selection unit configured to output any one among the plurality of delayed clock signals as a selected delayed clock signal in response to duty ratio information of the input clock signal, an edge control unit configured to generate a falling clock signal by controlling a falling edge of the selected delayed clock signal and to generate a rising clock signal by controlling a falling edge of the input clock signal based on information regarding a difference between lengths of a high duration and a low duration of the input clock signal, and a phase mixing unit for mixing phases of the falling clock signal and the rising clock signal and generating an output clock signal.
