Abstract: A booster circuit includes a boost converter configured to boost an input voltage and performs feedback control such that an output voltage becomes a set value on the basis of a voltage applied to a feedback terminal and an internal feedback reference voltage, a power supply unit configured to generate a reference voltage with a smaller error than the feedback reference voltage, and a control unit configured to compare a voltage corresponding to the output voltage of the boost converter with the reference voltage, and configured to output a control signal indicating a comparison result to the feedback terminal of the boost converter.

Abstract: A current output module includes a current output section configured to output a current, an AD conversion circuit configured to convert a detection voltage, which is a voltage according to the current output from the current output section, into a digital value, a controller configured to control a current output from the current output section on the basis of the digital value of the detection voltage output from the AD conversion circuit, and a reference voltage generator configured to generate a plurality of reference voltages. The controller includes a processor configured to cause the AD conversion circuit to convert each of the plurality of reference voltages into a digital value, and a corrector configured to calibrate the AD conversion circuit on the basis of each digital value obtained by conversion of the plurality of reference voltages.
