What is tpHL?
💡 Hint: Consider how outputs behave as they switch states.
True or False: An increase in load capacitance speeds up the propagation delay.

Challenge Problems
Push your limits with advanced challenges
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.
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.
