  • Publication number: 20240296319
    Abstract: Disclosed are an integrate-and-fire neuron circuit implemented to enable an integrate-and-fire operation with only a small number of devices by using bistable resistance characteristics of the same two heterojunction NPN devices, unlike a CMOS-based integrate-and-fire neuron circuit having a complex structure, and an operation method thereof. In one or more aspects, an integrate-and-fire neuron circuit and an operation method thereof can increase neuron integration in a system by implementing an integrate-and-fire operation of neurons using only three transistors and two capacitors, or two transistors, one resistor and one capacitor, can improve the efficiency of spiking neural network learning by controlling a fire threshold point of neurons through regulation of a gate voltage of the same two NPN devices, and can expect an increase in energy efficiency of the entire system through inhibition of excessive fire by implementing excitatory and inhibitory post-synaptic potentials.
