高阶锁相环系统的设计与仿真

Design and Simulation of High-Order PLL

对高阶环系统进行分析和推导,针对一种二阶有源积分的环路滤波器形式,提出了一种三阶锁相环的设计方法,并利用ADS等工具进行仿真和优化,采用CAD手段实现了高阶环的设计与性能仿真。

In this paper, the high- order PLL system was investigated and deduced. A method to design the three- order PLL system using a two- order active integral loop filter was put forward. The tools of ADS are used to simulate and optimize the three- order PLL system to realize a CAD way of the high- order PLL design and simulation
