Low voltage high Q VHF CMOS transistor-only active inductor

This paper describes circuit topologies that are suitable for realising very high frequency transistor-only active inductors in CMOS technology. Based on a low voltage topology, a novel VHF CMOS active inductor is proposed. The proposed inductor can achieve high Q with minimum circuit complexity, thus minimizing noise and power consumption. Compared to previously reported inductors, the proposed circuit achieves much higher Q for the same power consumption, noise and dynamic range.
