摘　　要：设计了一种基于65 nm CMOS工艺的毫米波宽带压控振荡器(VCO)。分析了应用于宽带VCO的宽带化技术。针对高频相位噪声性能恶化这一问题,提出并设计了一种等效阻抗渐变变压器,以优化VCO高频段相位噪声。该压控振荡器输出信号频率为20.4~40.2 GHz,覆盖24~26 GHz、38~39 GHz两个5G毫米波通信频段。全频带内,相位噪声小于-102 dBc/Hz,品质因子大于180.9 dBc/Hz。A millimeter-wave wide tuning range voltage-controlled oscillator circuit fabricated using the 65 nm CMOS process is introduced.The wideband technology applied to a VCO is analyzed.An equivalent impedance gradient transformer was proposed and designed to optimize radio frequency phase noise of the VCO to solve the problem of radio frequency phase noise.The output frequency of the voltage-controlled oscillation is 20.4-40.2 GHz,covering the 5G millimeter wave communication bands of 24-26 GHz and 38-39 GHz.The phase noise in the full band is less than-102 dBc/Hz,and the figure-of-merit in the full band is greater than 180.9 dBc/Hz.
