Abstract :
A small-signal and large-signal analysis was performed on a CMOS microwave VCO and the key contributors to its phase noise were determined. These analyses were verified for a 2.0 GHz, fully integrated L-C VCO in 0.6 μm CMOS technology and a phase noise of -103 dBc/Hz at 100 kHz frequency offset with DC power consumption of 22 mW was obtained. These noise analyses can be used to optimize the phase noise of the VCO for a given power consumption
