Abstract:
A waveform shaping circuit enhances a rise of a waveform of a voltage applied to a load and includes an input unit to which the voltage is input; a supply unit configured to apply the voltage input from the input unit to the load; a first resistor connected in series between the input unit and the supply unit; a second resistor branch-connected to a portion between the input unit and the supply unit; and a stub connected to the first resistor or the second resistor and including a transmission path of a given length configured to shuttle the voltage by transmitting and reflecting the voltage as a voltage wave.
