Abstract:
A duty cycle correction circuit is provided. The duty cycle correction circuit may include a correction circuit configured to correct a duty cycle of an external clock signal according to a locking signal. The duty cycle correction circuit may include a locking signal detection circuit configured to generate the locking signal for correcting the duty cycle of the external clock signal, using an internal clock signal generated in a semiconductor circuit.

Claim (Index 16):
A duty cycle correction circuit comprising:\n a repeater configured to retransmit a received external clock signal to predetermined circuit components in a semiconductor circuit; a comparator configured to generate a comparison signal by comparing a locking signal and the output signal of the repeater; a first duty cycle calibrator configured to adjust a duty cycle of the external clock signal according to the comparison signal; an oscillator configured to generate internal differential clock signals; a replica configured to delay the internal differential clock signals by the same delay time as a signal processing delay time of the repeater, and output signals including the delayed signals; a duty cycle detector configured to generate differential duty detection signals by detecting a duty difference between the output signals of the replica; a second duty cycle calibrator configured to calibrate the duty cycles of the internal differential clock signals according to the differential duty detection signals; and a locking signal detector configured to output a level at which the duty locking of the internal differential clock signals is completed, as the locking signal.
