Electronic neural circuit including at least one pre-neuron having an output voltage VA, and at least one post-neuron that are linked by at least one excitatory synapse having at least one switching input, wherein the excitatory synapse is supplied with power by the output VA, and receives, on its switching input, a switching signal VAwhose state is complementary to that of the output VA.

Switched artificial synapse

An optical sensor, especially an artificial retina, that includes at least one photosensitive cell. Each cell includes a integration capacitor, a read circuit the operation of which depends on the charge of the integration capacitor, at least one MOS transistor operating subthreshold, and the drain-source current of which influences the charge on the integration capacitor, and at least one photodiode operating in photovoltaic mode and connected to the gate of this transistor, such that the drain-source current of the MOS transistor depends on the optical power received by the photodiode.
