Abstract

A new second-order multi-mode multifunction filter configuration is introduced. This configuration uses a single current differencing buffered amplifier (CDBA) and, depending on topology, a total of four/five passive elements (two/three capacitors and two/three resistors). Current-mode (CM), voltage-mode (VM), transimpedance-mode (TIM) and transadmittance-mode (TAM) topologies are presented for realizing BP, LP and HP filter responses. The validity of the proposed filters is verified through PSpice simulations and experiments.
