Abstract
According to one embodiment, there is provided a semiconductor device comprising a first differential amplifier circuit. The first differential amplifier circuit includes a first transistor, a second transistor, a third transistor, a fourth transistor, a fifth transistor, and a sixth transistor. The second transistor's gate and drain are connected to the first transistor. The third transistor is diode-connected through the first transistor or diode-connected without passing through the first transistor. The fourth transistor is diode-connected through the second transistor or diode-connected without passing through the second transistor. The fifth transistor forms a first current mirror circuit with the third transistor. The sixth transistor is connected to a drain of the first transistor in parallel with the third transistor and forms a second current mirror circuit with the fifth transistor.
