Abstract
A 12GHz VCO fabricated in a 0.18µm SiGe BiCMOS technology with only CMOS devices, is presented. To improve tuning range and phase noise, a technique using strongly magnetic coupled LC tanks with fixed and tunable capacitive elements is proposed. The VCO achieves wide tuning range of 4.3GHz (36%) with only 4.5mW power consumption. The proposed VCO including buffer stage occupies a chip area of 0.17mm2, and can be easily integrated on-chip with other blocks.
提出了一种采用0.18 μ m SiGe BiCMOS技术,仅采用CMOS器件的12GHz压控振荡器。为了改善调谐范围和相位噪声,提出了一种采用具有固定可调谐电容元件的强磁耦合LC槽的技术。VCO实现了4.3GHz(36%)的宽调谐范围,功耗仅为4.5mW。所提出的包含缓冲级的VCO芯片面积为0.17mm2,并且可以很容易地与其他模块集成在片上。
