A wide-range programmable duty cycle corrector (DCC)

A very simple, wide range and programmable duty cycle corrector (DCC) is presented. SPICE simulation results show that the frequency range of the input signal is 250MHz to 1.6GHz, the duty cycle range of the input signal is from 30% to 70% and the programmable duty cycle of the output signal is from 30% to 70% in steps of 10%. The power consumption and p-p jitter are 4.9mW and 2.5ps at 1.6 GHz respectively. This circuit is simulated in 0.35um CMOS technology.
