Abstract
An analogue arithmetic unit according to an embodiment includes a plurality of input terminals, a voltage/current conversion circuit, a current addition circuit, a current/voltage conversion circuit, and a division circuit. The voltage/current conversion circuit exponentially converts each input voltage applied to each of the plurality of input terminals and outputs the converted input voltage as a current. The current addition circuit obtains a sum of the currents converted by the voltage/current conversion circuit. The current/voltage conversion circuit converts each of the currents and the sum of the currents into voltages. The division circuit calculates a ratio of the voltage obtained by converting each of the currents to a total voltage obtained by converting the sum of the currents.
