## Abstract A 5โGHz 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 ฮผm CMOS process, and the measured phase noise is โ122.7 dBc/Hz@1 MHz when operates at 4.936 GHz, with a po
## Abstract A novel lowโpower differential Colpitts voltageโcontrolled oscillator (VCO) is proposed and implemented in a 0.18โฮผm CMOS 1P6M process. The proposed circuit topology consists of two singleโended Colpitts LCโtank VCOs, and the differential VCO is obtained by using a crossโcoupled nMOS pa
