摘　　要：A fully integrated VCO and divider implemented in SMIC 0.13μm RFCMOS 1P8M technology with a 1.2 V supply voltage is presented. The frequency of the VCO is tuning from 8.64 to 11.62 GHz while the quadrature LO signals for 802.1 1 a WLAN in 5.8 GHz band or for 802.1 1b/g WLAN and Bluetooth in 2.4 GHz band can be obtained by a frequency division by 2 or 4, respectively. A 6 bit switched capacitor array is applied for precise tuning of all necessary frequency bands. The testing results show that the VCO has a phase noise of-113 dBc @ 1 MHz offset from the cartier of 5.5 GHz by dividing VCO output by two and the VCO core consumes 3.72 mW. The figure-of-merit for the tuning-range （FOMT） of the VCO is -192.6 dBc/Hz.A fully integrated VCO and divider implemented in SMIC 0.13μm RFCMOS 1P8M technology with a 1.2 V supply voltage is presented.
