APPLICATION NOTE 4345
Well Grounded, Digital Is Analog
By: Bill Laumeister

Abstract: An inexperienced designer may think that power decoupling capacitors and grounds are magic mystical
things that absorb every bad noise. They are not. This application note discusses proper capacitor selection. It
explains the failure of capacitors to decouple power buses above their self-resonance point. To illustrate the forces
and cha
