<p>Electronic circuit such as an adjustable resistance, a negative resistance, a filter or similar 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 means for controlling the intensity of the polarization current to determine the ohmic value of said intrinsic resistance. The invention is characterized in that the reference and output ports are directly connected to one another.</p> |
