摘要：
The present invention relates to a duty cycle correction circuit of a DLL circuit. According to the present invention, in an APDM, a voltage comparator of a duty cycle correction circuit operates without being reset. Therefore, although an internal power supply voltage is instantly changed in the APDM, the duty cycle of a DLL clock can be accurately set to 50%.
