Current-Mode Multifunctional Filter Utilizing Losses of Inductor Simulator

Abstract

In this paper, a simple configuration for simulating the inductance using voltage differencing current conveyor (VDCC) as an active element has been presented. The proposed inductance simulator circuit uses only one VDCC, one current amplifier (CA), and one grounded capacitor. The equivalent value of the realized simulator can be tuned electronically through the transconductance parameter and current gain of the VDCC and current gain through the CA. The proposed circuit behavior together with its application is demonstrated using PSPICE simulations with commercially active devices. Functionality of the proposed circuit is verified through its application in the second-order circuit. The circuit that behaves as a filter, has one input and standard three output responses such as low-pass filter (LPF), band-pass filter (BPF), and high-pass filter (HPF).
