What is static power dissipation in an integrated circuit (IC)?
The power consumed by the IC when it is actively switching between logic states.
The power dissipated due to the charging and discharging of load capacitances in the IC.
The power consumed by the IC when it is in a steady state, with no switching activity.
The power lost due to leakage currents in the transistors when the IC is active.
