This work presents design of a fully integrated Voltage Control Oscillator (VCO) implemented in 45 nm standard CMOS process. The designed LC VCO operates at 9. 06 GHz with 634. 28µW power consumption from 1 V supply. The design achieves phase noise as -97. 48dBc/Hz at an offset of 1MHz and the figure of merit (FOM) of the LC-VCO is calculated as -178. 60dBc/Hz for the un-buffered VCO. For buffered VCO the phase noise becomes -97. 69dBc/Hz at an offset of 1MHz and the FOM is -178. 81dBc/Hz.
