Broadband impulse generator

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.
