摘要

本文研究了低功耗LC-VCO设计中变压器反馈和正向体偏两种低功耗电路技术的优化方法。除了理论分析之外，采用这两种技术的低功耗、低电压x波段压控振荡器也已在标准0.18µm CMOS技术中实现。该VCO具有良好的FOM和191.4dBc/Hz，而核心电路从0.55V低电源电压中提取2.73mA的直流电流。其优异的性能可与目前报道的最佳x波段CMOS vco相媲美。

Investigation and optimization of low-power techniques in X-band CMOS LC-VCO design

This paper investigates the optimization method for two low-power circuit techniques in low-power LC-VCO designs: Transformer feedback and forward body-bias. In addition to theoretical analysis, a low-power, low-voltage X-band VCO using these two techniques has also been implemented in a standard 0.18µm CMOS technology. This VCO exhibits good FOM and of •191.4dBc/Hz while the core circuit draws a DC current of 2.73mA from 0.55V low supply voltage. The excellent performance can be compared with the best reported X-band CMOS VCOs.
