Abstract
A driving circuit includes an amplification circuit that outputs an amplified modulation signal and a level shift circuit. In the level shift circuit, when a reference potential of the amplified modulation signal is shifted to a second potential from a first potential, a second gate driver outputs a third gate signal for controlling a third transistor to be nonconductive and a fourth gate signal for controlling a fourth transistor to be conductive, then outputs the third gate signal for controlling the third transistor to be conductive and the fourth gate signal for controlling the fourth transistor to be nonconductive, and thereafter outputs the third gate signal for controlling the third transistor to be nonconductive and the fourth gate signal for controlling the fourth transistor to be conductive.
