摘　　要：A fully integrated wideband voltage-controlled-oscillator(VCO) based on current-reused topology is presented. The overall scheme contains two sub-VCOs, which are controlled by a switch to cover a wide output frequency range. Fabricated in TSMC 65 nm CMOS technology, the measured output frequency of the VCO ranges from 3.991 GHz to 9.713 GHz,achieving a tuning range of 83.5%. And the worst and best phase noise at 1 MHz offset are-93.09 dBc/Hz and-111.97 dBc/Hz, respectively. With a 1.2 V supply voltage, the VCO core consumes a current of 3.7-5.1 mA across the entire frequency range. The chip area is 0.51 mm^2, including the pads. Moreover, the proposed VCO provides a figure-of-merit-with-tuning-range(FOM_T) of-191 dBc/Hz to-197 dBc/Hz.
