摘要
A high-speed CMOS Phase/Frequency Detector (PFD) for faster frequency acquisition is presented An improved CMOS D-type master-slave flip-flop is described and adopted. Higher speed is attributed to the reduced node capacitances. Charge-sharing phenomena are circumvented. An input delay scheme is employed to achieve faster acquisition. The optimal delay for PFD maximum operating frequency is analytically studied and a design guide is given.(1)
