Abstract
A low power CMOS LC Voltage Controlled Oscillator (VCO) with body-biasing and Q-enhancement techniques is presented. This circuit was taped out by TSMC 0.18um 1P6M process. The measurement result of the VCO oscillation frequency range is from 4.92GHz to 5.7GHz, the tuning range of 14.7%. and the dc core current consumption is 1.78mA at a supply voltage of 1.4 V. The measured phase noise is -118dBc/Hz at 1MHz offset at the operation frequency of 4.94GHz.It achieves figure of merit (FOM) is -188.6dBc/Hz.
