Original Abstract

A novel solution of a fractional order low-pass type frequency filter is presented. The proposed structure comprises of two Double-Output Current Followers (DO-CFs), two Multi-Output Current Followers (MO-CFs) and two Adjustable Current Amplifiers (ACAs). The slope of the transition between the band-pass and band-stop region can be adjusted by intentional control of the order in range from 1 to 2 given by the change of values of resistors and current gains of ACA elements. The proposal is supported by PSpice simulation using transistor-level simulation models of employed active elements.
