摘要

介绍了一种用于低功耗WLAN应用的5ghz CMOS LC压控振荡器(VCO)，该振荡器采用CMOS 0.18um工艺制作。为了降低功耗，本文提出的VCO采用交叉耦合架构和通用升压配置。该VCO的测量结果显示，在1 MHz偏置时相位噪声为115.7dBc/Hz，调谐范围为4.25GHz ~ 5.12GHz(17%)，而在1.6V电源电压下功耗仅为3mW。核心面积为0.763mm × 0.616mm。

Design of low power VCO using Gm-boosted technique for WLAN applications

A 5 GHz CMOS LC voltage-controlled oscillator (VCO) for low power WLAN applications, fabricated using CMOS 0.18um process, is presented in this paper. To reduce the power consumption, the proposed VCO employs a cross-coupled architecture with Gm-boosted configuration. Measured results of the proposed VCO reveal phase noise of 115.7dBc/Hz at 1 MHz offset and tuning range of 4.25GHz∼5.12GHz (17%) while consuming only 3mW under the supply voltage of 1.6V. The core area is 0.763mm × 0.616mm.
