Realization of a Large Values Floating and Tunable Active Inductor.

This paper presents a new design for active inductor (AI) realization in addition to capacitance and resistance multipliers. The design uses one current conveyor (CCII +/-) and one dual-output transconductance amplifier(DO-OTA) and a grounded capacitor. The functionality of the design is confirmed using experimental verification and simulation. Simulation results show that the realized inductance is tunable be tuned from few mH to 2H and more and the multiplication factor for the resistance multiplier is more than 2200 while the capacitance multiplication factor is around 500. A CMOS version of the AI is designed and simulated using Tanner Tspice in 0.18 mu m CMOS technology. The simulation results confirm the functionality of the design.
