Abstract :
A low phase noise, low power, and wideband CMOS LC voltage controlled oscillator (VCO) with transformer feedback is presented. The measurement result of the VCO exhibits a tuning range of 28% form 4.39 GHz to 5.8 GHz at the supply voltage of 0.8 V. The figure of merit, core power consumption and output power are -193.1, 4.4 mW and -2.3 dBm, respectively. The phase noise is -124.3 dBc/Hz at the operation frequency of 5.8 GHz. The VCO is fabricated in TSMC 0.18 ¿m 1P6M CMOS process.
