ABSTRACT:
Current injection logic device with a system of Josephson diodes.
This system is constituted by N parallel branches, each having a first and a second Josephson diode in series, so as to provide a connection. All the first and second diodes are respectively connected to first and second main electrodes, the second electrode being earthed. The device also has M current inputs, respectively connected to M of the connections and an output connected to the first main electrode and which is to be raised to a logic level determined as a function of the values of currents injected by the inputs. In each branch provided with a current input, one or other of the diodes is shunted by a resistor, as a function of the envisaged application.
