Abstract :
A 1 V 3.8-5.7 GHz VCO was designed and fabricated in a 0.13 /spl mu/m SOI CMOS process. This VCO features differentially-tuned accumulation MOS varactors that (a) provides 40% frequency tuning when biased between 0 to 1 V, and (b) rejects common-mode noise such as flicker noise. At 1 MHz offset, the phase noise is -121.67 dBc/Hz at 3.8 GHz, and -111.67 dBc/Hz at 5.7 GHz. The power dissipation is between 2.3 to 2.7 mW depending on the centre frequency. When V/sub DD/ is reduced to 0.75 V, the VCO only dissipates 0.8 mW at 5.5 GHz.
