Abstract
In a case in which an input offset voltage of a main amplification circuit deviates from a predetermined range, a retaining operation of retaining an output voltage of a low pass filter in a sample and hold circuit stops, and an output voltage of the low pass filter is directly output to a correction signal supply circuit. As a result, for example, negative feedback control is not temporarily performed due to influence or the like of an excessive input voltage on the main amplification circuit, and in a case in which the input offset voltage of the main amplification circuit deviates from the predetermined range, a response delay due to the retaining operation of the sample and hold circuit does not occur, and the response speed of an offset correction circuit increases.
