Patent ID: 8310750

Claim:
A waveform shaping circuit that enhances a rise of a waveform of a voltage applied to a load, comprising: a first resistor connected to the load; a second resistor connected to the load; 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, wherein the stub is an open stub connected in parallel with the first resistor and includes: a dielectric substrate; a first transmission path as the transmission path of the given length provided on the dielectric substrate and connected to one side of the first resistor, wherein a portion of the first transmission path is cut out; and a second transmission path connected to one side of the second resistor and provided on the dielectric substrate so as to face the first transmission path with the dielectric substrate therebetween.
