Abstract
Disclosed is a spiking neural network circuit, which includes an axon circuit that generates first and second input spike signals, a synapse circuit that generates a first current based on the first input spike signal and a weight and generates a second current based on the second input spike signal and the weight, a capacitor that forms a first membrane voltage based on the first current, and a neuron circuit including a comparator and that resets the first membrane voltage, and after the capacitor further forms a second membrane voltage based on the second current, and the comparator includes a first input terminal and a second input terminal, receives the first membrane voltage through the first input terminal and a reference voltage through the second input terminal, generates a first spike signal based on a first comparison operation of the first membrane voltage and the reference voltage.
