OverviewTransient load decouplingDiscussionDecouplingSwitching subcircuitsPlacementExample usesSee also
Transient load decoupling as described above is needed when there is a large load that gets switched quickly. The parasitic inductance in every (decoupling) capacitor may limit the suitable capacity and influence the appropriate type if switching occurs very fast. Logic circuits tend to do sudden switching (an ideal logic circuit would switch from low voltage to high voltage instantaneously, with no middle voltage ever observable). So logic circuit boards of…
