Electronics Letters, 1981 A four-port active circuit called the current-voltage conveyor (CVC) is proposed and its properties are described. It can be used for realisation of controlled sources, negative impedance convertors and other active elements. It is shown how to obtain summing of voltages and currents using the CVC. The realisation of the CVC with OAs and OTAs is given.
