1. An arithmetic device comprising:
an input distribution signal generation circuit configured to receive a first electrical signal including an arithmetic result signal and propagate the first electrical signal through the input distribution signal generation circuit to generate an input distribution signal and a compensation signal based on the arithmetic result signal generated from a result of a multiplying-accumulating (MAC) calculation;
an output distribution signal generation circuit configured to receive a second electrical signal including the input distribution signal and propagate the second electrical signal through the output distribution signal generation circuit to apply the input distribution signal to an activation function to generate a first output distribution signal and a second output distribution signal; and
an output distribution signal compensation circuit configured to receive a third electrical signal including the first and second output distribution signals and the compensation signal and propagate the third electrical signal through the output distribution signal compensation circuit to compensate for the first output distribution signal based on the compensation signal, the first output distribution signal, and the second output distribution signal to generate a compensated distribution signal.
