    Abstract

    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%.
