【摘要】 提出一种品质因数（Q）-频率特性（Q-f特性）和对工作电压波动鲁棒性增强的新型有源电感。首先，通过回转器、直流偏置电路、分流支路三个构成模块的相互配合和它们的外部偏置端电压的协同调节，增强了Q-f特性，即实现了在同一频率下Q峰值相对于电感值可大范围独立调节以及在不同频率下Q峰值保持基本不变的2种Q值特性。其次，通过设置由感知单元与放大单元构成的稳压模块，增强了电感值和Q峰值对工作电压波动的鲁棒性。结果表明，在3.84 GHz频率下，Q值可从636调节到4 032，调节率高达533%，而电感值变化率仅为0.13%；在3.84 GHz、2.40 GHz和1.54 GHz不同频率下，分别取得4 032、4 039和4 043的高Q峰值，Q峰值变化率仅为0.2%；电感值和Q峰值的工作电压敏感度分别为0.011 nH/mV和20.0/mV。更多还原

【Abstract】 A novel active inductor with enhanced Q-f characteristics and strong robustness to supply voltage fluctuation is presented. Firstly,a gyrator,a direct current bias circuit and a shunt branch are constructed,and the cooperativeness among these modules and the joint tuning of their external bias voltages enhanceQ-fcharacteristics,i.e. theQpeak value can be tuned independently in a wide range with respect to the inductance value at the same frequency and theQpeak value can keep almost unchanged at different frequencies. Secondly,a voltage regulator module,composed of sensing unit and amplification unit,is employed to strengthen the robustness of the inductance value andQpeak value to the fluctuation of supply voltage. The verification results indicate that at the frequency of 3.84 GHz,theQpeak value can be adjusted from 636 to 4 032 with the large tuning rate of 533%,while the inductance variation is of only 0.13%. Under the frequencies of 3.84 GHz,2.40 GHz and 1.54 GHz,theQpeak values can be high up to 4 032,4 039 and 4 043 respectively with the variation of only 0.2%. The supply sensitivities of inductance value andQpeak value are 0.011 nH/mV and 20.0/mV respectively.更多还原
