A dual-band LC voltage-controlled oscillator in 0.13μm CMOS technology

A dual-band, low phase-noise LC voltage-controlled oscillator (VCO) has been demonstrated in a 0.13μm CMOS process. The operating frequency of the dual-band VCO covers from 1.51GHz to 1.92GHz and from 2.13GHz to 2.73GHz. The proposed VCO features phase-noise of -116.4dBc/Hz and -121.5dBc/Hz at 1MHz offset frequency for both low corner and high corner end of the low-band operation. For high-band operation, phase-noise performance of -109.6dBC/Hz and -118.2dBc/Hz at 1MHz offset frequency are achieved. At 3V supply voltage, the power dissipation is 54.3mW for the low-band operation and 51.5mW for the high-band operation.
