Abstract :
In the recent era of wireless communication, requirement of high frequency is increasing day by day and for OFDM based system data rates should be high. Signal coming from different sources contain noise due to which there is error in phase and frequency and we get a deviated output. In view of this there is need to design frequency synthesizer which would provide a low locking time, low settling time, moderate value of damping factor to provide a efficient frequency response at the output end. The proposed design is for 4 GHz frequency which is implemented in IEEE 802.11 (a) WLAN standard and OFDM technology.
