On the implementation of the floating simulators employing a single active device

Abstract In this paper, two circuits for realizing floating inductor (FI), floating capacitor (FC) and floating frequency-dependent negative resistor (FDNR) simulators depending on the passive component selection are introduced. Both of the developed circuits employ a single active device called modified current feedback operational amplifier (MCFOA) and a minimum number of passive elements. The FIs and FCs use a grounded capacitor thus the developed circuits are very suitable for fully integrated circuit (IC) design. Also, the proposed circuits require no critical passive component matching conditions and/or cancellation constraints. The simulation results using SPICE program are also given to verify the theory to exhibit the performance of the first circuit.
