Circuit simulating biological neural network based on similar MOS luminescent devices

A circuit simulating a biological neural network based on similar MOS luminescent devices belongs to the technical field of semiconductor integrated circuits and biological neural networks. The circuit comprises more than two basic neural units and light transmission paths, wherein each basic neural unit comprises neural synapses, of the biological neural network, which are simulated by optical reception and conversion devices which receive optical signals and convert the optical signals into electric signals, and neurons, of the biological neural network, which are simulated by similar MOS luminescent devices which convert electric signals into optical signals, and the light transmission paths simulate axons of the biological neural network. The more than two basic neural units are connected serially or/ and in star-shape through the light transmission paths, so as to simulate the biological neural network. The circuit is compatible with the CMOS process, small in area, high in efficiency and convenient for integration, and is of a great importance to research and development of artificial intelligence.
