摘　　要：为解耦RC常数的限制,将电感峰值技术应用于环形振荡器中。对传统的环形振荡器结构进行改进,设计了两款GHz级别的CMOS环形压控振荡器(VCO)。采用0.13μmCMOS制造工艺,在0.13V电源电压下进行Spice仿真。仿真测试结果表明,两个应用了电感峰值技术的VCO均有很高的振荡频率,分别达到3～7.5GHz和7.5～8.6GHz,还具有良好的线性度及抑制电源纹波的能力,电源电压波动敏感度分别为0.015%/1%@2.65GHz和0.024%/1%@8.43GHz。In order to decouple the limitation of RC constant,this paper introduces inductive shunt peaking technology into ring oscillator.Two GHz-level voltage controlled oscillators（VCO） were designed.Both of the structures were improved based on traditional structure.Under 0.13um CMOS process,1.3 V power supply.Simulation results in SPICE indicate that both of the VCOs that base on inductive peaking technology have very high oscillator frequency,up to 3～7.5 GHz and 7.5～8.6 GHz.Otherwise the both VCO have a good linearity and Frequency pushing,power pushing sensitivity is 0.015% / 1%@2.65 GHz和0.024% / 1%@8.43 GHz.
