Date Dec. 8, 1994Electronic circuit comprising at least one first second-generation current conveyer consisting of a mixed translinear loop and a plurality of current mirrors. The conveyer includes a high impedance reference port, an input port with an intrinsic resistance equivalent to the output resistance of the equivalent Thevenin generator, seen by the input port and polarized by a polarization current, an output port with a current corresponding to that of the input port and a current controller for controlling the intensity of the polarization current to determine the ohmic value of the intrinsic resistance. The invention's reference and output ports are directly connected to one another.
