Summary:在TSMC0．18μmRFCMOS工艺下设计了一个Ku波段电感电容压控振荡器，该电路采用NMOS交叉耦合型，结合滤波技术降低相位噪声，并利用开关电容阵列为其扩频，使电路获得卓越的性能。后仿真结果表明，该电路实现了10GHz-14GHz的宽调频，在整个频带内其相位噪声低于-112dBc／Hz在1MHz的偏移处；在1．8V的电压下，核心电路工作电流为5mA。
Bibliography:This paper proposes a Ku-band NMOS differential cross-coupled LC VCO with the TSMC 0.18 μm RF cmos pro- cess.To lower the phase-noise, the filtering technique is used, and to widen the tuning range, the switched-capacitor array is used, which have improved the performance. Post-simulation has shown that the tuning range is from 10 GHz to 14 GHz, and the phase noise is lower than -112 dBc/Hz @1 MHz offset in the whole frequency band. The VCO core consumes 5 mA current under 1.8 V supply voltage.
