Abstract
According to one embodiment, a semiconductor device includes a first current mirror having an output end coupled to a first node, a second current mirror having an output end coupled to a second node, a third current mirror having an input end coupled to the second node and an output end coupled to the first node, a fourth current mirror having an input end coupled to the first node, and an output driver that generate a current based on the fourth current mirror. A current flows to the first current source changes at a first ratio with respect to temperature, a current flows to the second current source changes at a second ratio having a negative correlation with respect to temperature, and an absolute value of the first ratio is smaller than that of the second ratio.
