In this paper, we investigate the effects of signal transitions between layers in a 4-layer printed circuit board (PCB) with a stack-up of signal-ground-ground-signal (S-G-G-S) . We observe impedance changes and cavity noise, leading to ground bounce when the signal transitions from the top layer to the bottom layer [1]. To mitigate these effects, we examine the difference in crosstalk when the return path for the signal is present and when it is removed. We use a high-frequency structure simulator (HFSS) and Advanced Design System (ADS) to simulate and model the system in frequency domain, extract S-parameter data, and plot graphs to verify our results. The main objective of this project is to demonstrate the importance of proper return path design for high-speed signals in multi-layer PCBs.
