Abstract: An artificial neuron device according to an embodiment of the present disclosure includes a first resistor connected between an input terminal and a first node; a capacitor connected between the first node and a ground terminal; a threshold switch connected between the first node and a second node; and a second resistor connected between the second node and the ground terminal, wherein, when an input voltage of a certain level is applied to the input terminal by time, a membrane potential occurs at the first node and a spike current flows through the second node. According to present disclosure, the artificial neuron device expresses the Integrate-and-Fire function, the rate coding ability, the SFA characteristics, and the chaotic activity of the biological neuron, and therefore may be widely used for the artificial neuron network device, the large-scale brain-inspired computing system, and the artificial intelligence (AI) system.
