Yet More On Decoupling, Part 5—When Harry Regulator Met Sally Op-Amp

This paper is the fifth 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. The focus of this paper is the signal chain from op amp to load, and the interaction of load current, power supply, and amplifier output.
