Abstract: To reduce settling time of PLL, an attempt to optimize the parameters has been proposed in this paper. The transient responses of various Phase Locked Loop (PLL) frequency synthesizer have been comparied with their active and passive poles effect. These results are presented on a type-II 3rd order PLL frequency synthesizer employing a 3rd order MASH sigma delta modulator. The simulation results show the improved performance of the fractional frequency synthesizer for the communication system. These results have been simulated using Advanced Design System(ADS) tool.
