Abstract: The technology of PLL is widely used in various domain of communication.Charge Pump PLL consists of PFD,CP,LPF,VCO and frequency divider module.Grounded on the non-ideal effect of Charge Pump PLL,an optimized design has been carried out.A corresponding acting model has been created,in the process of system design,simulated and proved though simulink.Accomplished by CMOS Process and the entire system  meets the design demand and works well.

Key words: frequency synthesis, charge pump PLL, optimized design, acting model
