Abstract

A semiconductor integrated circuit includes a first input terminal configured to input a first input voltage, a second input terminal configured to input a second input voltage, a differential amplifier configured to generate a differential output voltage by amplifying a differential input voltage obtained from a difference between the first input voltage input by the first input terminal and the second input voltage input by the second input terminal, a switch configured to electrically connect or cut off the first input terminal and the second input terminal, and a sample hold unit connected to a power supply which generates a reference voltage and configured to generate an offset correction voltage of the differential amplifier based on the differential output voltage and the reference voltage when the first input terminal and the second input terminal are electrically connected by the switch.
