چکیده
A new CMOS LC Voltage Controlled Oscillator (VCO) for IEEE 802.11a application with low phase noise and consumed power less than 1mW is presented. This circuit was taped out by TSMC 0.18um 1P6M process. The measured phase noise is -115-88dBc/Hz at 1MHz offset at the operation frequency of 5.815GHz. And the dc core current consumption is 0.71mA at a supply voltage of 1.4 V. Its figure of merit (FOM) is -191dBc/Hz.

Design and Simulation of an X Band LC VCO
In this paper, a systematic method for the circuit parameters design of a monolithic LC Voltage Controlled Oscillator (VCO) is reported. The method is based on the negative resistance generation technique. As a result, a VCO has been designed in 0.18um CMOS technology using a conventional VCO structure to obtain the optimum values for the phase noise and power consumption. The simulation result...
