摘　　要：采用互补型交差耦合结构,设计了一个可工作于WiMAX（IEEE 802.16e,2.469~2.69GHz）和LTE（2 496~2 690 MHz）无线射频收发机的压控振荡器（VCO）。采用TSMC 0.18μm CMOS工艺对VCO电路进行设计及仿真。仿真结果表明,在1.2V电源电压下,压控振荡器的功耗为1.44mW,振荡频率变化范围为2.43~2.69GHz,可调范围约为10.15%,相位噪声为-120.4dBc/Hz@1 MHz,FOM为-186.9,满足WIMAX/LTE无线通信系统的要求。Based on complementary cross-coupled structure,a voltage controlled oscillator for WiMAX（IEEE802.16 e,2.469-2.69GHz）and LTE（2 496-2 690MHz）RF transceiver was proposed.The VCO was designed and simulated with TSMC 0.18μm CMOS process.The simulation results showed that the power consumption was1.44 mW from a 1.2Vsupply voltage,the oscillation frequency range was from 2.43 GHz to 2.69 GHz,the tuning range was about 10.15%,the phase noise was-120.4dBc/Hz at 1MHz offset frequency,the FOM was-186.9.The proposed VCO could meet the requirements of WIMAX/LTE wireless communication systems.
