Multifunction filters using three current conveyors
A new current conveyor based filter topology with ten different realisation possibilities, using only positive type second generation current conveyors and only grounded passive components, is presented. For all possibilities, no element matching conditions are imposed. The filters permit orthogonal adjustment of quality factor Q and resonant angular frequency ?0. All circuits exhibit high input impedance thus enabling easy cascadability. The passive sensitivities are shown to be low. The functionality of the circuits is tested on a filter design example by experiment.
