首发时间:2008-12-05
摘要: 本文在分析锁相环中的环路滤波器技术的基础上,提出了对无源环路滤波器的设计方法。采用了基于锁相环频率特性分析的方法,实际了电荷泵锁相环中的无源低通滤波器电路。文章讨论了基本二阶无源滤波器的设计方法,并推广到三阶无源滤波器的情况,同时给出了采用这种方法设计的电荷泵锁相环的仿真结果。

The Design of Passive Filter for Phase-Locked Loop
Abstract:Based on the analysis of loop filter of phase-locked loop,a design method of the passive loop filter is investigated in the paper. An analysis of a frequency-domain design technique for passive filters in charge pump phase-locked loops is presented. The design method for basic passive filters is discussed with emphasis on the design of a 2 and 3 order passive low-pass filter.Simulations of a loop filter designed using this method show good results in a practical phase-locked loop realization.
Keywords: Charge pump Phase-locked loop Passive low-pass filter Loop filter
