SUPERCONDUCTING NEURON FOR MULTILAYER PERCEPTRON Russian patent published in 2020 - IPC G06N3/06 G06N3/08 H03F19/00 H01L39/22 

FIELD: physics; electricity.

SUBSTANCE: invention relates to cryogenic micro- and nanoelectronics, including to element base of artificial neural networks. Proposed superconducting neuron for a multilayer perceptron comprises a Josephson junction connected galvanically to the main inductance, which is galvanically connected both to the shunt inductance and to the auxiliary inductance; means for setting input signal in form of magnetic field, connected inductively with main and auxiliary inductances; means of output signal detection in the form of current value connected inductively with shunting inductance. Besides, proposed device provides conversion of input magnetic flux at input F_in (created by means of magnetic field setting) into current at output I_out (read by means of detection) according to law described by sigmoid function.

EFFECT: technical result consists in improvement of speed and energy efficiency of superconducting neuron.
