Floating inductance, FDNR and capacitance simulation circuit employing only grounded passive elements

Abstract

A circuit for realizing floating inductance, grounded to a floating admittance converter, floating frequency dependent negative resistance (FDNR) and floating capacitance simulators depending on the passive element selection is presented. The proposed circuit employs only grounded passive elements and second-generation current conveyors (CCIIs) but it requires single passive component matching. Replacing second-generation current controlled conveyors (CCCIIs) instead of the CCIIs in the developed circuit, an electronically tunable floating inductor with bias currents can be obtained. Also, replacing dual X second-generation current conveyors (DXCCIIs) instead of the CCIIs in the introduced circuit, an electronically tunable floating inductor with bias voltages can be obtained. Under non-ideality conditions, the proposed circuit can realize a lossless floating inductor and a capacitor depending on the passive element choice. Simulation results using SPICE program are given to verify the theory.
