提出了一种性能多种重构的高频压控有源电感(HFVCAI)。电路主要由第一回转回路、第二回转回路以及调控支路构成, 且第一回转回路和第二回转回路并联, 调控支路与第一回转回路连接, 两个回转回路均配置了外部调控端。通过协同调节3个外部调控端, 可对HFVCAI的性能进行3种重构: 在高频工作区能够对电感值进行大范围调控, 且同时能保持Q值有较大值; 在不同频率下能够同时保持Q峰值和电感值基本不变; 能够实现在对工作频带大范围调控时, 电感值峰值保持基本不变。结果表明, 在5.10~6.60 GHz高频区, 电感值的调控范围大于27 nH, 且Q值可保持大于10; 在4.72 GHz、5.10 GHz和5.46 GHz高频下, 分别取得了1 063、1 053和 1 033 的Q峰值, 变化率仅为2.8%, 且电感值分别为202 nH、198 nH和191 nH, 变化率仅为 5.4 %; 工作频带能在6.02 ~ 7.67 GHz之间调控, 变化率高达27.4 %, 而电感值峰值在404 ~ 395 nH之间变化, 变化率仅为2.2%。

A high frequency voltage controlled active inductor (HFVCAI) with multiple reconfigurable performances was proposed, which was mainly composed of a first gyration loop, a second gyration loop and a tuning branch circuit. And the first gyration loop was in parallel with the second gyration loop, and the tuning branch circuit was connected to the first gyration loop. Furthermore, both gyration loops were equipped with external tuning terminals. Therefore, taking full advantage of combinational adjustment of the three external tuning terminals, three reconfigurable performances of the HFVCAI could be achieved as follows: had a wide tuning range of the inductance and simultaneously kept a large and constant Q value in the high frequency operation region; had almost unchanged Q peak values and inductances at different frequencies; had a wide range of adjustment of the operation frequency bandwidth without the change in the peak value of inductance. The results showed that in the high frequency region of 5.10~6.60 GHz, the tuning range of inductance was greater than 27 nH, and the Q value could remain greater than 10. At the high frequencies of 4.72 GHz, 5.10 GHz and 5.46 GHz, the Q peak values could be high up to 1 063, 1 053, 1 033 respectively with the variation of only 2.8%, meanwhile, the inductances were 202 nH, 198 nH and 191 nH with the variation of only 5.4%. The operation frequency bandwidth could be adjusted from 6.02 GHz to 7.67 GHz with the large variation of 27.4%, while the peak value of inductance was varied from 404 nH to 395 nH with the variation of only 2.2%.
