“Design and analysis of frequency synthesizer with low power ring oscillator for wireless application”

Abstract

In wireless medium, requirement of high frequency is increasing day by day. For high frequency based system data rates should be high. In unguided media, as signal travels a long distance and due to interference of noise, there is error in phase and frequency and we get a deviated output. In view of this, We are motivated to design a low power 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 aspect is for high frequency which is implemented in IEEE 802.11(a) WLAN standard and OFDM technology, WCDMA, Bluetooth technology, high frequency processor. We have used Microwind 3.1 45nm technology and ADS as design tool to execute propose design.
