Abstract: Provided is a neuromorphic arithmetic device. The neuromorphic arithmetic device may include a synapse circuit, a metal line having an inherent capacitance component, an oscillator, a comparator, and a capacitance calibrator. The synapse circuit may be configured to perform a multiplication operation on a PWM signal and a weight to generate a current. The metal line may include a metal line capacitor in which a charge of the current is stored. The oscillator generates a plurality of pulses on the basis of the charge stored in the metal line capacitor. The comparator may compare a frequency of the plurality of pulses and a target frequency, and may generate a control signal on the basis of a result of the comparison. The capacitance calibrator may adjust a capacitance value of the metal line capacitor on the basis of the control signal.

Abstract: An electronic device includes first to n-th cells (‘n’ is an integer of 2 or more) that receive spatial-temporal input signals that indicate an event unit in a time window, a summation circuit that sums first to n-th cell signals recorded in the first to n-th cells for each of first to m-th unit times (‘m’ is an integer of 2 or more) dividing the time window to generate first to m-th summation signals, and an encoding circuit that compares each of the first to m-th summation signals with a threshold value to encode the spatial-temporal input signals into a code of the event unit.
