Abstract:
A waveform shaping circuit includes a first variable gate voltage circuit that controls a minimum voltage of a pulse voltage based on a drain current or a source current of a field effect transistor, the pulse voltage having a positive or negative value and being applied to a gate of the field effect transistor, and a second variable gate voltage circuit that controls a maximum voltage of the pulse voltage based on the drain current or the source current.

Claim (Index 3):
