    Abstract: Disclosed is a spike neural network circuit, which includes an axon generating a spike input, a synapse performing a weight calculation and generating a membrane signal based on the weight calculation, and a neuron accumulating the membrane signal to generate a spike output, and the neuron includes a firing unit that compares a potential of a membrane node where the membrane signal is accumulated with a reference potential and fires based on the comparison result, membrane capacitors connected to the membrane node, a switch controller that outputs switching signals based on the firing of the firing unit, switches that connects each of membrane capacitors to one of a power supply voltage and a ground voltage in response to the switching signals, and a spike output generator that generates the spike output based on the plurality of switching signals and the firing of the firing unit.

    Abstract: The present disclosure relates to a neuromorphic arithmetic device. The neuromorphic arithmetic device may include first and second synapse circuits, a charging/discharging circuit, a comparator, and a counter. The first synapse circuit may generate a first current by performing a first multiplication operation on a first PWM signal and a first weight, and the second synapse circuit may generate a second current by performing a second multiplication operation on a second PWM signal and a second weight. The charging/discharging circuit may store charges induced by the first current and the second current in a charging period, and may discharge the charges in a discharging period. The comparator may compare a voltage level of the charges discharged in the discharging period and a level of a reference voltage. The counter may count output pulses of an oscillator on the basis of a result of the comparison by the comparator.
