Abstract
A differential amplification circuit and a method corrects an offset voltage derived from a variance in resistances. With first and second input terminals brought to the same potential and set to a potential different from a reference potential, the resistance value of resistors is adjusted so that an output potential and the reference potential will be substantially equal to each other.
