文章采用PSPICE软件，建立了锁相环仿真模型。从环路滤波器、闭环传递函数、相位裕量和指令解调四个方面，对所建模型进行仿真对比、参数扫描分析，最终确定锁相环路的参数，完成了环路的稳定性和解调特性的优化。最后，对优化后的环路参数进行温度扫描分析和蒙特卡罗分析，验证了该参数的可生产性。

Ab Model of phaselocked loop is built based on PSPICE. To get the best optimus parameters in stability and demodulation of the phase-locked loop, parameter scans of simu- lation are used to contrast and optimize the key-parameter, in four aspects： loop filter, transfer function of closed loop, phase margin and demodulation of dictate. Finally, the simulation of temperature scan and Monte Carlo is used to prove that the parameters of phaselocked loop are fitted to produced.
