Pseudo-Differential Fractional-Order Frequency Filter

Abstract

This paper describes a pseudo-differential fractional (1+α)-order frequency filter. Thestructure operating in voltage-mode and and works as a low-pass filter. The proposed structure ischaracterized by high input impedance, high output impedance and the minimum number of passiveelements when all are grounded. The properties and functionality of the (1+α)-filter are verifiedby simulations.
