In this article, a digitally controlled band-switching voltage controlled oscillator (VCO) is designed and fabricated using TSMC 0.18 μm CMOS technology. Design considerations regarding the power requirement and the phase noise of the VCO are discussed. Eight bands are set by three bits, with one bit controlling switching inductors, and two bits controlling switching capacitors. The VCO covers 2.9–3.45 GHz and 3.6–4.3 GHz using varactors for continuous frequency tuning. Phase noise of the VCO stays constant around -110 dBc/Hz at 1 MHz offset for all bands. The fabricated VCO consumes 11 mA of current with 1.8 V supply voltage and has a small size of 730 μm × 660 μm. © 2008 Wiley Periodicals, Inc.
