Simple multifunction filter realizations with current conveyors

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