Abstract:
A trimming circuit which comprises a shunt circuit having two shunt resistors and two shunt ON/OFF switches and connected in parallel with a series resistor circuit. The middle point of the shunt circuit is connected to a connection point of the series resistor circuit, the resistance ratio thereof with respect to the connection point being equal to the resistance ratio of the shunt resistors.
