By Bhanu Kapoor A decoupling capacitor (DeCap) is used in power-managed designs to decouple a power domain from the effects of power switching in a related domain. A switching sub-circuit (a power domain or a voltage island) can mess up the power supply line upon which other sub-circuits or domains depend upon. When a load switches into a circuit, the circuit tries to increase its curre... » read more
