A low-power dual-band voltage-controlled oscillator (VCO) using a fourth-order resonant technique implemented in 0.18-μm CMOS process is presented in this letter. By utilizing a fourth-order LC-type resonant network and a current-reused technique, the proposed VCO operates in the dual-band mode and improves the overall performance. The tuning ranges of band 1 and band 2 are from 3.39 to 3.68 GHz and from 7.2 to 7.57 GHz controlled by a controlled-voltage VC, respectively. The measured phase noises at 1 MHz frequency offset are −117.39 dBc/Hz and −113.58 dBc/Hz for output frequencies of 3.68 and 7.21 GHz, respectively. Besides, the figures-of-merit (FOM) at 3.68 and 7.21 GHz output frequencies are −182.5 and −184.5 dBc/Hz, respectively. The proposed VCO core consumes 4.2 mW from a 1.2-V supply.
