摘要
在线性锁相环ＣＡＤ仿真的基础上，提出了用通用电路分析程序（如ＩｓＳｐｉｃｅ、Ｐｓｐｉｃｅ等）对锁相环非线性特性进行分析与仿真的方法，并通过一个具体的正弦型鉴相器例子分析了不能用线性模型分析方法解决锁相环非线性捕捉过程，通过仿真提出了用ＣＡＤ模型判别该类环路的频率捕捉带方法。
Based on the simulation of linear PLL,this paper puts forward an improved method to analyze and simulate the nonlinear performance of PLL.Some PCbased circuit CAD programs (such as IsSpice,Pspice,etc.)can be used to model the nonlinear PLL,as a illustration,one instance with sine PD and step frequency hopping is simulated with this method,from it we can watch the locking process of a PLL circuit which is impossible for a linear PLL model analyses,further more,a magic phenomenon can be found to determine whether it will lock^out.
