DXCCII-based grounded inductance simulators and filter applications

Abstract

In this paper two new grounded inductance simulators based on DXCCII suitable for operation in 30 kHz30 MHz frequency range, are presented. The proposed circuits both employ only a single dual X second-generation current conveyor (DXCCII) active device accompanied with three and four passive elements, respectively. The accuracy of the simulated inductors is verified by implementing them in some filter applications. Also, a novel multi-input single-output universal filter derived from one of the new grounded inductance simulators is simulated to demonstrate the functionality of the proposed circuit. Simulation results using AMS 0.35 µm CMOS process technology parameters are included. © 2011 Elsevier Ltd.
