Abstract
An electronic device inputs a voltage from each of a first and a second constant voltage sources, amplifies the inputted voltage, and converts the inputted voltage or a voltage amplified by an amplifier into a digital value. Using a first and a second digital values based on the inputted voltage, and a third and fourth digital values based on the inputted, amplified and converted voltage, an amplification factor of the amplifier and an offset voltage of the amplifier are calculated, and the amplifier is corrected based on the calculated amplification factor and offset voltage.
