Abstract:
A drive signal generator includes a drive signal generator that generates a drive signal for driving a capacitive load. In the drive signal generator, a set of a first MOSFET and a second MOSFET which are electrically connected in series between a wire of a high potential and a wire of a low potential is arranged in plurality in series. A part or all of the first MOSFETs and the second MOSFETs in the plurality of sets have different sizes from each other.
