Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What is tpHL?
- The delay from low to high
- The delay from high to low
- The average delay
💡 Hint: Consider how outputs behave as they switch states.
Question 2
True or False: An increase in load capacitance speeds up the propagation delay.
- True
- False
💡 Hint: Think how much time it takes to charge a larger capacitor.

Challenge Problems
Push your limits with challenges.
Question 1
A NAND gate shows tpHL of 15 ns and tpLH of 25 ns. Adjust the NMOS widths in an optimization scheme to balance these delays and explain your rationale.
💡 Hint: Consider how resistance varies with width.
Question 2
If you had a gate with a load capacitance that doubled from 50 fF to 100 fF, explain how that would affect both tpHL and tpLH in practical terms.
💡 Hint: Think how long it takes to fill an extra-large water tank.
