Based on traditional common source - common gate - common drain (CS-CG-CD) active inductors (AI), an improved AI is proposed. Firstly, both the first feedback loop with parallel resistance and the second feedback loop with small size transistor were introduced between CG transistor of the negative transconductor and CD transistor of the positive transconductor. Secondly, the tuning branch circuit was introduced between CS transistor of the negative transconductor and CD transistor of the positive transconductor. Furthermore, the cooperation among above different modules and the joint adjustment of their external tuning terminal voltages realized two reconfigurable performances as follows: 1) high Q peak values could be achieved and tuned independently relative to the inductance values in a large range at the same frequency; 2) high Q peak values could be obtained and kept almost unchanged at different frequencies. The verification results show that at the frequency of 5.81 GHz, the Q peak value can be adjusted from 1 132 to 15 491 with the tuning percentage of 1 268.5%. Meanwhile, the inductance values change from 7.65 nH to 7.67 nH with the variation of only 0.26%. Under the frequencies of 5.72 GHz, 7.12 GHz and 7.93 GHz, the Q peak values can be high up to 1 274, 1 317 and 1 310 respectively, and the variation percentage is only 3.38%. Meanwhile, the large inductance values of 7.62 nH, 8.08 nH and 8.81 nH can be obtained respectively. It consumes about 38.61 mW.
