【摘要】：针对传统共漏-共栅-共源(CD-CG-CS)有源电感的不足,结合有源网络和受控辅助电阻支路,设计了一款具有大电感值,且可在不同频率下获得高Q峰值和在同一频率下对Q峰值进行大范围调谐的新型有源电感。基于TSMC 0.18μm CMOS工艺,利用安捷伦公司的射频电路设计工具ADS软件对其进行仿真验证。仿真结果表明:当调节有源网络偏置时,在2.48~2.87 GHz的工作频带内,取得了10.89~13.16 nH的大电感值,在2.48,2.74和2.87 GHz三个不同频率下,分别取得了9 997,4 015和2 717的高Q峰值。当调节受控辅助电阻支路偏置时,在工作频率为3.10 GHz下,取得了11.65~17.61 n H的大电感值,Q峰值可在616~3 823之间进行大范围调谐。用Cadence Virtuoso工具进行版图设计,新型有源电感的版图面积较小,仅为21.5μm×34.4μm。
[Abstract]:Aiming at the shortcomings of the conventional CD-CG-CS active inductors, a large inductance is designed by combining the active network with the controlled auxiliary resistance branch. A new type of active inductor with high Q peak at different frequencies and a large range tuning Q peak at the same frequency can be obtained. Based on the TSMC 0.18 渭 m CMOS process, the software ADS of Agilent Company's RF circuit design tool is used to verify the simulation. The simulation results show that when the bias of the active network is adjusted, the large inductance of 10.89 and 13.16 NH is obtained in the operating frequency band of 2.48 ~ 2.87 GHz, and the high Q peaks of 9 997N 4 015 and 2 717 are obtained at three different frequencies of 2.48 nm 2.74 and 2.87 GHz respectively. When the bias of the controlled auxiliary resistance branch is adjusted, the large inductance Q peak of 11.65 ~ 17.61nH can be tuned in a large range between 616N and 3823 at the operating frequency of 3.10 GHz. The layout design with Cadence Virtuoso tool shows that the layout area of the new active inductor is relatively small, which is only 21.5 渭 m 脳 34.4 渭 m.
