A 5-GHz LOW-PHASE NOISE CMOS VCO WITH SWING BOOSTING TECHNIQUE

A 5-GHZ CMOS VCO with improved phase noise is proposed in this article. A gate voltage boosting technique is realized with only one inductor. The proposed VCO is fabricated in 0.18 gin CMOS process. and the measured phase noise is -122.7 dBc/Hz@1 MHz when operates at 4.936 GHz, with a power dissipation of 5.28 mW from 1 V supply.
