Phase-Locked Loops Design by ADS and Matlab

This paper describes the design and simulation of Phase-Locked Loops(PLL) based on ADS. In order to overcome the shortage of data-analyzing and simulating ability of this software,a method for dealing with the output data of ADS via MATLAB is proposed. Then,the feasibility and practicability of this method is proved by an example of LPM signal generated by PLL.
