Abstract
In exploring transmission lines and signals, it is clear that signals that are close to each other have both capacitive and inductive coupling between them. It turns out that this is both good news and bad news. In this chapter, we will start with the good news and introduce differential signaling. In the next chapter, we will break the bad news and discuss crosstalk. One common method for better signal integrity is to move to differential signaling. This seemingly simple change, using both a positive and negative waveform in a matched set, eliminates the need for an intact ground plane, takes care of return current, manages ground bounce, and generally improves signal integrity.
