Abstract
A first correction voltage generation circuit provides a first positive or negative correction voltage for correcting an input voltage. A second correction voltage generation circuit provides a second correction voltage identical in polarity to the first correction voltage in accordance with the first correction voltage. The second correction voltage is generated to have a temperature coefficient reverse in polarity to a temperature coefficient of the first correction voltage.
