Lets take a look at the various low power techniques in use today.
I would classify them into 2 categories

  • Structural Techniques
    • Voltage Islands
    • Multi-threshold devices
    • Multi-oxide devices
    • Minimize capacitance by custom design
    • Power efficient circuits
    • Parallelism in micro-architecture
  • Traditional Techniques
    • Clock gating
    • Power gating
    • Variable frequency
    • Variable voltage supply
    • Variable device threshold
Which one of the above techniques are aimed at reducing Dynamic Power and Leakage Power?

Dynamic Power Reduction
  • Clock Gating
  • Power efficient circuits
  • Variable frequency
  • Variable voltage supply
Leakage Power Reduction
  • Minimize usage of Low Vt Cells
  • Power Gating
  • Back Biasing
  • Reducing Dynamic Power
  • Reduce Oxide Thickness
  • Use FINFET's
