Abstract

A VCO is one of the key building blocks of RF wireless communication because its phase noise performance will make an impact on the sen-sitivity level and blocker characteristic of a receiver. A Voltage Controlled Oscillator (VCO) is used for implementing a frequency synthesizer to provide the Local Oscillator (LO) signal for an up/down converter in a RF transceiver or a data and clock recovery in a high speed data links with a Phase-Locked Loop (PLL). Parameter which are important in context of designing LC VCO are phase noise,tuning range,FOM,supply voltage. One of the parameter which is very important to be focused on is phase noise. The inductor and capacitor is connected in parallel at the drain of NMOS transistor to reduce the phase noise as well as to improve the figure of merit which indicate the performance of LCVCO is implemented in this thesis. In this thesis, 30 GHz LC VCO is shown with the help of which better phase noise and FOM is obtained. Whole circuit is implemented on 65nm technology. A 8.4 GHz tuning range is obtained with tuning voltage of 0-1V. The power consume by the whole circuit is 1mW which is better than the other listed papers shown in the references. The supply voltage is 1V.
