A Lossless Simulated Floating Inductor Based on the Second-Generation Current Conveyors

Abstract

In this study, a new lossless simulated floating inductor (SFI) is proposed. The proposed circuit contains three non-inverting second-generation current conveyors. It consists of a capacitor and three resistors, but all the passive elements are floating. The proposed SFI requires one passive element matching condition. A second-order low-pass filter (LPF) is given as an application example. All the simulations are performed through the SPICE program. Also, some experiments for the proposed SFI and second-order LPF filter are conducted. All the simulations are performed by using the macro model of the AD844, and all experimental tests are achieved by using the AD844s. © 2025 Istanbul University. All rights reserved.
