Abstract
A 5.2 GHz CMOS LC voltage-controlled oscillator (VCO) for UWB receiver, fabricated using CMOS 0.18µm process, is presented in this paper. The tuning range of the proposed VCO is mainly broadened by novel negative resistance and tapping inductance techniques. Measured results of the proposed VCO reveal phase noise of −116.708/Hz at 1 MHz offset and tuning range of 4.567GHz∼5.832GHz (24.32%) while consuming only 3.92mW under the supply voltage of 0.8V. The core area is 0.732mm × 0.633mm.
