A new current-mode (CM) single input three outputs (SITO) multifunction filter topology is presented, which employs only three FTFNs or OFAs and five passive elements. From this topology, two filter circuits can be derived selecting the passive elements properly. The proposed filter realizes three filter functions simultaneously all at high impedance outputs. No component matching is required and all the passive sensitivities are low.
