Abstract
According to one embodiment, there is provided a semiconductor device including a first amplifier and a second amplifier. The first amplifier has an input terminal to receive a first signal and an output terminal to output a second signal. The second amplifier is configured to receive the first signal and a correction data, to generate a correction signal according to the first signal and the correction data, and to output the generated correction signal to the output terminal of the first amplifier so as to add the first signal and the generated correction signal.
