The invention relates to an electronic device for conveying digital information (= 0 =, = 1 =) for a long distance, that comprises a transmitter (100-101) generating current pulses, and at least one reception means or receiver assembly (150) converting the received current pulses into logic pulses compatible with the operation of standard logic electronic circuits. The receiver (150) includes a pair of magneto-resistive stacks including at least one hard ferromagnetic layer and one soft ferromagnetic layer separated by a non-ferromagnetic intermediate layer, the hard layer of each magneto-resistive stack being trapped in a magnetic state perpendicular to an axis of easy magnetisation used as a reference for the soft layer of the same stack, the soft layer of each magneto-resistive stack having a magnetic orientation that can be modulated by the magnetic field generated by the current pulses from the transmitter in order to induce a modification of the transverse resistance of the stack that is sufficient for triggering an electric signal, wherein the resistance modifications of the two stacks crossed by a same pulse interact in order to generate a differential signal. |
