Leakage Power

Leakage Power

Power Consumption consists of Dynamic Power and static Leakage Power. In this blog, we will talk mainly about static Leakage power dissipation.

Leakage Power depends upon…

  1. Gate length
  2. Oxide thickness
  3. Threshold voltage etc.

Leakage Power can be divided in two parts…

  1. Leakage Power in stand by mode
  2. Leakage Power in active mode

Static Leakage Power (stand by) mode saving technique

  • Power gating

Static Leakage Power (active) mode saving technique

  • Dual Vth
  • Multi mode Vth
  • Optimal stand by input vector selection
  • Transistor stacking
  • Body bias
