ON THE DVCC AND THE BOCCII AS ADJOINT ELEMENTS

The Differential Voltage Current Conveyor (DVCC) with its two polarities namely DVCC- and DVCC+ are reviewed together with their pathological element representations. Their two adjoint building blocks are the Balanced Output Current Conveyor (BOCCII) and the Balanced Output Inverting Current Conveyor (BOICCII) are also discussed with their pathological element representations. The universal CMOS circuit realizing these four building blocks is also included. The Nodal Admittance Matrix (NAM) stamp for the DVCC-, DVCC+, BOCCII and BOICCII are also given. Among the four basic building blocks considered the DVCC- is the only floating building block. Examples are given showing that some of the reported filters are related to each other by the adjoint network theorem.
