An improved CMOS high Q value active inductor by adding one resistor in the feedback path is proposed. This resistor generates a gain factor that can compensate for the internal loss and the inductance of the active inductor. Simulation results show that a dramatic improvement in the Q value up to 1E8, inductance value from 5nH to 7.5nH, 1.2E-8Ω of minimum total equivalent loss in the range of 0.5GHz to 2.5GHz, and 2.5mW power consumption under 2.5 V supply voltage has been observed.
