Abstract :
An all-digital 50% duty cycle corrector (DCC) is presented. The features of the proposed DCC include a wide operation frequency range, a wide input duty cycle range for the input clock, and a short locked time to recover the duty cycle of 50%. This digital DCC has been implemented in a 0.35mum 2P4M CMOS process. The acceptable duty cycle and frequency range of the input clock is 25%-75% and 250MHz-600MHz, respectively. The measured peak-peak jitter is 17.3ps at 600MHz. Besides, this DCC saves the power consumption by turning off a half delay line. Its power consumption is 16mW at 600MHz
