Generation of CCII and CFOA filters from passive RLC filters

Ahmed M. Soliman

Open publisher page 29 citations

Abstract

It is shown that low-sensitivity active filters employing the current conveyor (CCII) or the current feedback operational amplifier (CFOA) as the active element can be generated directly from passive RLC filters. New current-mode filters using CCII and voltage mode filters using the CFOA are generated from three alternative passive RLC filters. The proposed circuits have the advantage that compensation of the dominant parasitic elements of the CCII or the CFOA can be easily achieved. PSpice simulation results are included.
