摘要
Abstract
A monolithic 10GHz LC voltage-controlled oscillator (VCO) is implemented in standard 0. 25μm CMOS tech- nology. The VCO adopts an optimized symmetric circular inductor with center-tap, an accumulation-mode MOS (A-MOS) varactor in series with a passive metal-isolator-metal capacitor (MIM-CAP) and a tail current source with an LC filter to operate with high-frequency and low-noise resulting in-103. 2dBc/Hz at 1MHz offset from carrier frequency of 10.2GHz and approximately 11.5% tuning range. With a 3.3V supply voltage,the core circuit consumes 9.9roW. The chip area is 0.67mm×0.58mm.关键词
