In the paper, a transformation method of frequency filters using Balanced Output Transconductance Amplifiers (BOTA) into equivalent filtering structures with Universal Current Conveyors (UCC) is shown. A newly designed multifunction filter using two BOTAs was derived from the general autonomous circuit and transformed into a UCC-based frequency filter. The properties of the proposed second-order multifunction filter were subjected to an AC analysis in the OrCAD software and the BOTA-based circuit to experimental measurement.
