Yet More On Decoupling, Part 2: Ring the Changes, Change the Rings

This paper is the second in a six-part series discussing power-supply decoupling and bypass capacitors. Extending a previous four-part series, this series looks at interactions between supply and capacitor, capacitor materials, and simulation models. This second installment discusses ringing and other voltage transient effects examined with a small test-current step, as well as the effect of a capacitor dielectric.
