This paper describes a three-stage Voltage Controlled ring Oscillator (VCO) based on 0.35 μm CMOS standard technology. The VCO was designed for a transmitter operating in the 863-870 MHz European band for Wireless Sensor applications. A voltage VCTRL controls the oscillation frequency of the VCO. Simulation results of the fully differential VCO with positive feedback show that the estimated power consumption, at desired oscillation frequency and under a supply voltage of 3.3 V, is only 7.48 mW. The proposed VCO exhibits a phase noise lower than -126 dBc/Hz at 10 MHz offset frequency.
