摘　　要：根据GSM系统标准中关于相位噪声和频率调谐范围的指标要求,采用无尾电流LC振荡结构和开关电容阵列设计了一款适用于GSM/EDGE便携式产品上的压控振荡器。电路采用TSMC 0.18μm CMOS工艺实现,在3.3V电源电压下的仿真结果表明:电路的工作频率覆盖了3296~3980MHz,输出电压峰峰值为5.32V@3622MHz,调谐增益为32MHz/V,频偏20MHz处的相位噪声为-155.37d Bc/Hz。设计的VCO完全满足GSM/EDGE系统要求。Based on the requirements of phase noise paper designs a voltage-controlled oscillator suitable and frequency tuning range of the GSM system standard, this for GSM/EDGE handset RFIC. This circuit uses the topology of no-tail current source and switched-capacitor array and has been designed in TSMC 0.18 μ m CMOS process. At a supply voltage of 3.3V, the simulation results show that the operating frequency covers 3296~3980MHz, the peak value of output voltage is 5.32V@3622MHz with the tuning gain of 32MHz/V. The phase noise is -155.37dBc/Hz at 20MHz offset. It will satisfy the requirements of GSM/EDGE application.
