Abstract :
An optimal loop parameter design method of charge pump PLLs for jitter transfer characteristic optimization is proposed. Based on the linear model of charge pump PLLs, the relationship between a PLL´s loop parameters and jitter transfer characteristic is illustrated. Using the proposed optimal design method, a design example is given and the expected simulation result is obtained.
