What is dynamic and static power?

Energy is required to charge and discharge the load capacitance. This is called dynamic power because it is consumed when the circuit is actively switching. Even when the gate is not switching, it draws some static power. Because an OFF transistor is leaky, a small amount of current Istatic flows between power and ground, resulting in a static power dissipation.

How to Calculate Static Current?
