Yet More On Decoupling, Part 3—Some Gain, Some Pain
This paper is the third 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 third paper addresses the question of whether or not designers should be concerned about the wobbling supply voltage that analog components demonstrate when connected. It focuses on a staple ingredient of the analog designer’s toolbox: the op-amp.
