1. A broadband impulse generator, comprising:
a first delay line configured to receive an input signal and include a plurality of first delay elements connected in series with each other, wherein a total number of the plurality of first delay elements is 2n−1;
a second delay line configured to receive the input signal and include a plurality of second delay elements connected in series with each other, wherein a total number of the plurality of second delay elements is 4n−3;
an oscillation signal generator coupled to the first delay line and configured to generate an oscillation signal having a plurality of pulses during a target impulse duration based on the input signal and output signals of the first delay line, wherein n is a total number of the plurality of pulses included in the oscillation signal;
an envelope signal generator coupled to the second delay line and configured to generate a plurality of envelope signals having a delay duration with each other and having a voltage level during the target impulse duration, based on the input signal and output signals of the second delay line, wherein a total number of the plurality of envelope signals is n; and
an impulse signal generator configured to generate an impulse signal having the plurality of pulses during the target impulse duration based on the plurality of envelope signals and the oscillation signal.
