Fully differential current-mode filter based on MDDCC

A novel modified multi-output differential difference current conveyor (MDDCC) and the related CMOS circuit are proposed in this paper. Basic filters including low-pass and band-pass employing the current conveyors are built up. The performances of the filters are analyzed and simulated, and the results show that the proposed circuits are effective. The MDDCC circuits combine the advantages of differential difference amplifier (DDA) and the second generation current conveyor (CC II) and are suitable for full integration.
