How Does the Package PDN Impact Power Integrity?

Whenever we say something to the effect of “components can’t work without a correctly designed PCB,” we only have to look at component packaging for evidence. It is true that component packages come with parasitics that affect signal integrity, but there is one area that we don’t often look at in terms of component packaging: power integrity.
