The fastest way to fix or prevent a problem is to identify its root cause and fix it at the source. Ground bounce is a type of cross talk related to return path discontinuities. We will look at a few examples of design features that cause ground bounce, and how to avoid this problem in your next product. We will use measurements of two board designs, one done correctly and one with ground bounce errors to verify our best design practices. After we explore the root cause and how to prevent ground bounce, you should never suffer this problem again.
