This paper presents new topology of multifunction voltage-mode filter using differential difference current conveyors as active elements. The structure bases on the idea of the Akerberg-Mossberg (AM) filter, i.e. the integrators in the structure are always realized only by two active elements, which provides better phase compensation for the filter. Compared to the AM OpAmp based filter, the newly proposed structure features with high-impedance inputs, low-impedance output, and three basic frequency responses (low-, band-pass, and bandreject). The mutually independent control of quality factor Q and characteristic frequency w0 is possible by means of passive elements, however, the electronic tunability can be achieved by the use of current-controlled counterparts. Spice simulation results agree well with the theory.
