Abstract

A low phase noise, power efficient VCO using UMC 0.18μm CMOS technology has been proposed in this paper. The proposed VCO has a tuning range of 9.71GHz to 9.9GHz, with a phase noise of -79.88 dBc/Hz @ 600kHz offset. The Vtune ranging between 1V - 1.5V generates sustained oscillations. The maximum power consumption of the VCO is 11.9mW using a supply voltage of 1.8V with ±10% variation.
