EE Design: Bypass Capacitor Resonances

Bypass capacitors – the components designers put in to help with dips in power due to switching digital circuits (and the components the factory tries to get rid of).

John Dunn writes on EDN about all the capacitive factors in a circuit, that they are non-ideal (they have resistance & inductance also making for resonant circuits) and what all those resonances might do if one appears at your clock frequency.

See the full treatment in this EDN article.
