This paper describes an MOS current-mode, voltage-controlled oscillator (VCO) circuit that potentially operates with a 2 V supply voltage, 500 MHz oscillation frequency, and -90 dBc/Hz phase noise at the 1 MHz offset. It also has an improved oscillation frequency linearity of the control voltage and 11 mW power dissipation. The oscillation frequency reached 920 MHz when the supply voltage was increased to 3 V.
