This document discusses power dissipation in circuits. It outlines that the objective is to discuss sources of power dissipation including static and dynamic power dissipation. Static power dissipation occurs even when a circuit is idle and includes leakage currents through transistors. Dynamic power dissipation is related to switching behavior and charging/discharging of capacitances.
