Abstract: A fully integrated 3GHz low-power and low-phase-noise voltage-controlled oscillator (VCO) with a self-biasing current source was implemented in a standard 0.18μm CMOS process.A trade-off between noise and power was realized through the optimization of the improved current source.The VCO can be tuned from 2.83 to 3.25GHz with a 13.8% tuning range.The measured phase noise at 1MHz offset is -111dBc/Hz at a frequency of 3.22GHz while the core circuit draws less than 2mA from a 1.8V supply voltage.These results make the circuit suitable for a 5GHz wireless local area network (WLAN) receiver and 3.4 to 3.6GHz world interoperability for microwave access (WiMAX) application.
