摘要： A broadband impulse generator includes a first delay line and a second delay line that receive an input signal and include a plurality of delay elements connected in series with each other, an oscillation signal generator that generates an oscillation signal having a certain number of pulses during a target impulse duration based on the input signal and an output signal of the first delay line, an envelope signal generator that generates a plurality of envelope signals having a delay duration with each other and having a certain voltage level during the target impulse duration, based on the input signal and an output signal of the second delay line, and an impulse signal generator that generates an impulse signal having the certain number of pulses during the target impulse duration based on the plurality of impulse signals and the oscillation signal.
