| Abstract: | In order to simulate charge pump PLL in frequency hopping systems, several methods are introduced and compared. The emphasis is on the event-driven model which can simulate the charge pump PLL quickly and efficiently. When the model is used to simulate the stability and setting time of the charge pump PLL, some improvements are made to run it faster. Other issues such as the relation between different models and some detailed aspects of implementation are also discussed. |
