Most of the work done on current controlled conveyor (CCCII) based continuous time filters has been in either current mode or voltage mode domain. Architectures that can work in mixed mode may be useful from IC realization viewpoint and application adaptability. This paper presents two generalized mixed mode configurations that use two DO-CCCII/MOCCCII, two capacitors and two resistors. The circuits are capable of realizing all generic filter functions: low pass, band pass, high pass, notch and all pass. PSPICE simulation results are presented.
