Abstract
A first transistor and a second transistor have control terminals coupled to each other. A current mirror circuit supplies a current having the same amount as that of a current Iflowing through a first path including the second transistor to a second path including the first transistor and supplies a current having a predetermined number of times m of a current amount of the current Iof the first path to a third path separate from the second path. The third transistor and a fourth transistor are provided on the third path. The third transistor has a source coupled to one end of the first transistor, and the fourth transistor has a gate coupled to a gate of the third transistor. A resistor is provided between a source of the fourth transistor and one end of the second transistor.
