CIRCUIT NEUROMORPHIQUE IMPULSIONNEL IMPLEMENTANT UN NEURONE FORMEL

摘要

An impulse-neuron-type neuromorphic circuit comprises a capacitor (C_mem) having a membrane voltage (V_mem), a first action comparator (1) for comparing the membrane voltage with a first action voltage (V_act, V_{threshold_high}), a first regulation comparator (4) for comparing the membrane voltage with a first regulation voltage (V_reg), a device for reinitialising the membrane voltage (3) a register of threshold exceeds (5) and a regulator (2). The regulator is configured: in case of exceeding the first regulation voltage (V_reg V_{threshold_low}) by the membrane voltage, to control the device for reinitialising the membrane voltage (3) and modify the register of threshold exceeds (5); and in case of exceeding the first action voltage (V_act V_{threshold_high}) by the membrane voltage, to control the device for reinitialising the membrane voltage (3) and query the register of threshold exceeds to decide whether or not to generate an action potential (S_pa) on an output of the neuromorphic circuit.
