摘要 设计和分析了一种低电压CMOS压控振荡器,对设计的电路进行理论分析和模型建立,并使用仿真工具对电路进行验证和优化。设计中主要考虑相位噪声和调谐宽度等指标,通过采用电感电容滤波技术以及合理调整电路结构和元器件参数,使相位噪声和调谐宽度均达到了较高的性能指标。结果表明,在1.2 V工作电压下,设计的VCO的尾电流为3 mA,输出振荡频率为2.24~2.57 GHz,中心频率约为2.4 GHz,调谐范围达到13.7%。 A low noise CMOS voltage controlled oscillator was designed and analyzed based on CSMC process.The basic theory and small signal model for the VCO were introduced.The performance of the VCO′s phase noise and tuning rang were optimized by the LC noise filtering technology,proper circuit struc-ture and device parameter.The circuit was simulated under supply voltage of 1.2 V.The frequency of the VCO ranges from 2.24 GHz to 2.57 GHz,the tail current is 3 mA,and the tuning range is about 13.7%.
