In a buffer device a cross couple circuit includes a first power synthesis section in which a source of a first source follower and a drain of a first source-grounded amplifier are connected and a second power synthesis section in which a source of a second source follower and a drain of a second source-grounded amplifier are connected. A first bias circuit adjusts voltage of gates of the first source-grounded amplifier and the second source-grounded amplifier so as to make common-mode voltage of output from the first power synthesis section and output from the second power synthesis section equal to reference voltage. A second bias circuit applies compensation voltage to gates of the first source follower and the second source follower so as to control variation in voltage applied to the gates of the first source follower and the second source follower.
