- 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.
