Abstract :
A 2GHz wide input dynamic range (25%-75%) duty cycle corrector (DCC) circuit with ±2% output duty cycle accuracy is presented. This DCC circuit supports input frequency ranging from 1GHz to 2GHz. The proposed circuit is implemented in 45nm low voltage (0.9V to 1.4V) digital CMOS process. Presented DCC consumes only 1.4mW and occupies 0.01 mm2 area. Built-in-self test method is used to test this circuit in production and shows 99.98% pass percentage in silicon.
