The present invention discloses a duty correction circuit for and method of enabling a clock signal and a clock bar signal phase transited from the clock signal by a phase difference of 180° to obtain a duty of 50%. The duty correction circuit includes: a duty check block for determining the duty of a clock signal, and generating a control signal indicating a determination result; and a duty correction block for receiving the clock signal or a clock bar signal, having a phase difference of 180° from the clock signal, correcting the duty of one of the clock signal or the clock bar signal according to the control signal from the duty check block, and outputting the duty-corrected signal. The method includes several steps, which reflect the procedure for correction of the duty.
