Abstract
A semiconductor device includes: a boosting section configured to output a second voltage boosted from a first voltage; a voltage lowering section configured to output a lowered voltage that has been lowered from the second voltage by a predetermined voltage; a first buffer amp including a non-inverting input terminal connected to an output of the voltage lowering section; a second buffer amp including a non-inverting input terminal that is input with the first voltage; and a difference output section configured to output a voltage corresponding to a difference between output of the first buffer amp and output of the second buffer amp.
