摘要
在共源共栅-共漏有源电感的基础上,联合采用调制晶体管和双反馈回路,提出了一种可在不同频率下获得高的品质因子(Q)峰值,且分别可在大、小范围内粗调和细调电感值的新型宽频带可调谐有源电感。基于TSMC 0.18μm CMOS工艺,利用ADS设计软件进行验证。结果表明,该有源电感在0~8.15GHz的工作频率范围内,调节主回路的偏置电压,在频率为4.0,4.85,5.95GHz时,分别获得1 154,666和1 293的高Q峰值。当Q值大于20时,其频率带宽均大于1.5GHz,可以在43~132nH之间粗调电感值的峰值。调节从回路的偏置电压,在5.95GHz固定频率下,获得418~3 517的高Q峰值,且可以在10%比例范围内细调电感值的峰值。
Based on the common source,common gate,common drain（CS-CG-CD）topology,a novel wideband tunable active inductor with high Q（quality factor）peak values at the different frequency was presented,and its inductances could be changed in a large or small range by coarse tuning or fine tuning respectively.The active inductor featured a combination of regulated transistors and dual feedback loops.Based on the TSMC 0.18μm CMOS process,the active inductor was verified by ADS.The simulation results showed that,by adjusting the bias voltage of the master circuit,the active inductor could operate in the 0~8.15 GHz band,and the Q peak values could be adjusted to as high as 1 154,666,1 293 respectively at the frequencies of 4.0 GHz,4.85 GHz,5.95 GHz.When the Qvalue was above 20,the frequency bandwidths were all greater than 1.5 GHz,and the peak inductance could be tuned from 43 nH to 132 nH for coarse tuning.By adjusting the bias voltage of the slave circuit,the Q peak values were up to 418~3 157 at a fixed frequency of 5.95 GHz.The peak inductance could be tuned by 10%for fine tuning.
