Multi-input differential current conveyor, CMOS realisation and application

The adjoint circuit of a multiple output second-generation current conveyor (MOCCII) is investigated. It is found that the adjoint circuit of MOCCII is an multi-input differential current conveyor (MIDCC). A CMOS realisation of the MIDCC with three plus-type input terminals and two minus-type input terminals is described. As an example of applying the MIDCC, the transforming of a current-mode filter using MOCCIIs to its adjoint voltage-mode filter using MIDCCs is discussed.
