Abstract
A circuit includes a third current mirror, through which a current obtained by adding a first reference current copied by a first current mirror and a second reference current copied by a second current mirror is made to flow; a reference resistor of a first type, through which the first reference current obtained by subtracting the second reference current from one output of the third current mirror is made to flow; and a reference resistor of a second type, through which the second reference current obtained by subtracting the first reference current from the other output of the third current mirror is made to flow. By the third current mirror, voltage drops at the reference resistors of the first type and the second type are the same, and the second reference current is set to be inversely proportional to the resistance value of the reference resistor of the second type.
