Abstract
A semiconductor device includes an amplifier that has an output terminal and that outputs via the output terminal a signal commensurate with an input signal fed to the amplifier, a signal conductor that is connected to the output terminal and that conducts a target voltage signal based on the output signal of the amplifier, a shield conductor that is laid along the signal conductor, and a shield drive circuit that controls the voltage on the shield conductor based on the target voltage signal.
