6 sample questions

Question 1.
What does Vdd stand for?
Show hintHide hint
Think about the voltage that powers circuits.
Question 2.
How does reducing Vdd affect dynamic power?
Show hintHide hint
Recall the formula related to dynamic power.
3Question 3.
What is the relationship between Vdd and dynamic power?
- Dynamic Power is inversely proportional to Vdd.
- Dynamic Power is independent of Vdd.
- Dynamic Power is proportional to Vdd squared.
Show hintHide hint
Consider how power changes when you alter the voltage.
4Question 4.
True or False: Lowering Vdd never impacts performance.
- True
- False
Show hintHide hint
Think about what happens when you decrease voltage in your circuits.
Question 5.
Propose strategies to optimize Vdd in a digital circuit while maintaining performance. Explain your reasoning.
Show hintHide hint
Think about scenarios in mobile and portable electronics.
Question 6.
Given that reducing Vdd can greatly reduce dynamic power, calculate how much power would decrease if Vdd is reduced from 1.2V to 0.9V in a circuit with a capacitance of 5pF.
