Grounded and floating impedance simulators employing a new active element

Abstract

In this paper a newly proposed active element namely Dual X current conveyor differential input transconductance amplifier (DXCCDITA) is used in designing two grounded inductance (GI) simulators and a generalized immittance simulator topology which can realize floating inductor (FI), floating capacitor (FC) and floating resistor (FR) based on passive elements selected. All the designed simulators require only a single active element and minimum number of passive components one/two for implementation. The proposed simulators enjoy tunability property. None of the proposed simulators require passive component matching conditions for realization. To demonstrate the workability of the simulators they are used in design of a current mode (CM) low pass filter circuit and second order voltage mode (VM) band pass filter. The simulations are performed using 0.35μm TSMC CMOS technology parameters in Hspice program.
