Question 1.
What is dynamic power in low-power circuits?
Show hintHide hint
Think about how power is consumed during activity when circuits are switching.
Question 2.
Describe one trade-off in low-power circuit design.
Show hintHide hint
Consider how reducing certain parameters affect speed.
3Question 3.
Which of the following reduces dynamic power in low-power circuits?
- Increasing V_dd
