Before revision: Switching power dissipation is directly proportional to the switching activity (α), load capacitance (C), Supply voltage (V), and clock frequency (f) as: P = α .C.V².f Switching activity means transition to different levels.
After revision: Switching power dissipation is directly proportional to the switching activity (α), load capacitance (C), Supply voltage (V), and clock frequency (f) as: P = α ·C·V2·f Switching activity means transition to different levels.
