Abstract: Since the performance of a charge pump PLL (CP-PLL) is strongly influenced by the pump current magnitude in the pump ON interval, this paper examines the effect of linearly increasing pump current on the transient response of the CP-PLL. It has been established through the numerical solution of the system equation and a simulation experiment using MAT-LAB software, that the process of pump current ‘‘modulation’’ may be used to enhance the transient behaviour of the CP-PLL.
