Abstract :
In this paper, the ground bounce (GB) effect in PCBs is characterized and presented in both the power/ground and the trace/ground configurations. A generalized 2-D transmission line equation (GTLE) model is used to solve the problems. Simulation results confirm that GB is induced as a result of the resonant behavior. In certain situations, GB gives rise to white noise in parts of the PCB structure
