Abstract
A semiconductor device comprising: a voltage generator configured to generate a voltage; a first analog-to-digital (AD) converter configured to convert an analog value based on a voltage generated by the voltage generator into a first digital value; and a second AD converter configured to convert an analog value based on a voltage generated by the voltage generator into a second digital value, wherein the voltage generator generates voltages by dividing a power supply voltage by resistive elements.
