10.3.3. Power Consumption

Try these first

1. 1.

   What is dynamic voltage scaling?

   Hint

   Think about how voltage changes affect power consumption.

2. 2.

   Name one advantage of clock gating.

   Hint

   Consider what happens when a part of a circuit is inactive.

3. 3.

   What technique lowers voltage to save power in circuits?

   • Clock Gating
   • Dynamic Voltage Scaling
   • Power Gating

   Hint

   Think about managing voltage during varying loads.

4. 4.

   True or False: Clock gating turns off power to an entire circuit.

   • True
   • False

   Hint

   Focus on the difference between power and clock signals.

5. 5.

   Design a hypothetical low-power device that uses DVS, clock gating, and power gating. Discuss how each method contributes to overall power efficiency.

   Hint

   Consider how each technique can reduce different types of power consumption.

6. 6.

   Evaluate the impact of using sub-threshold CMOS technology in an automotive sensor application. What would be the pros and cons?

   Hint

   Think about the trade-offs of power versus reliability in critical applications.
