• Simulations were performed using ADS software.
• Experimental generation and measurement of the pulse waveform were conducted.

Main Results:

• The designed pulse generator achieved a peak-to-peak amplitude of 1.88 V and a pulse duration of 307 ps.
• Minimal ringing was observed, with a measured value of -22.5 dB.
• A high degree of agreement between simulated and measured results was achieved.

Conclusions:

• The proposed SRD-based pulse generator effectively minimizes ringing.
