中文摘要	为了拓宽CMOS LC VCO的频率覆盖范围,很多工作都集中在扩展LC谐振回路中的电容覆盖.但通过对该VCO在调频状态下的分析表明,除了LC乘积的覆盖范围,在改变输出频率时维持交叉耦合MOS管的工作状态稳定也是获得宽带振荡器的条件之一.固定尺寸的交叉耦合MOS管结构不能满足后一个条件.将交叉耦合MOS管结构分为可开关调节的若干段可以有效地解决上述问题.通过VHF超宽频带CMOS LC VCO的具体设计表明,新电路结构可以获得突破性的频率覆盖.; Many efforts have been applied to extend the capacitance coverage in the LC tank for the purpose of ultra broadband CMOS LC VCO design.But the analysis of the tuning situation shows that the varactor change shifts the working state of the oscillator.It is discovered that besides the tuning range of capacitance in the LC tank,another restriction on the broadband CMOS differential VCO is the characteristic of the cross-coupled MOS pair which must be adjusted accompany with the varactor tuning to maintain the oscillation state.Dividing the cross-coupled MOSFET pair into switchable parts is a practice and effective method to meet the later condition.The design example of a VHF CMOS LC VCO demonstrates that the new schematic can get a breakthrough in the tuning range performance.; 国家自然科学基金资助项目(60475018,60372021); 国家重点基础研究发展(973)计划资助项目(G2000036508)
