Abstract
According to one embodiment, in a first differential amplifier circuit of a semiconductor device, a first transistor receives an input signal at the gate. A second transistor forms a differential pair with the first transistor. The second transistor receives a reference signal at the gate. A third transistor is connected in series with the first transistor. A fourth transistor is connected in series with the second transistor. A fifth transistor is disposed on the output side. The fifth transistor forms a first current mirror circuit with the fourth transistor. A sixth transistor is connected to the drain of the second transistor in parallel with the fourth transistor. The sixth transistor forms a second current mirror circuit with the fifth transistor. A first discharge circuit is connected to the source of the sixth transistor.
