Abstract
A driver includes a first driving circuit and a second driving circuit. The second driving circuit includes a computation amplifier, an output capacitor, a first feedback capacitor, and a second feedback capacitor. The computation amplifier is composed of a transistor with a breakdown voltage lower than the breakdown voltage of a transistor making up the first driving circuit. The output capacitor is disposed between an output node of the computation amplifier and the signal supply line. The first feedback capacitor is disposed between an inverting input node of the computation amplifier and the signal supply line. One end of the second feedback capacitor is coupled to the inverting input node of the computation amplifier.
