To lower the operation frequency of a voltage-controlled delay line (VCDL), this DLL adopts the dividers, an edge combiner, and the multiple VCDLs. A duty cycle correction circuit is presented to maintain the output duty cycle of 50%. This DLL has been fabricated in 90-nm CMOS process. The measured peak-to-peak jitters at 8 GHz are 11.44 and 6.67 ps before and after calibration, respectively. The power dissipation at 8 GHz is 18 mW for a supply voltage of 1.2 V, and the measured output duty cycle variation is less than 3%. © 2008 IEEE. |
