Challenge Problems
Push your limits with challenges.
Question 1
Analyze the increase in propagation delay due to added parasitic capacitance. Your calculated capacitance added is 500 fF. If the switching current is 50 µA, what impact does this have on delay?
💡 Hint: Look at the relationship between RC time constant and delay.
Question 2
Given a circuit measuring t_PLH and t_PHL allows for understanding where delays are most pronounced, how would you assess if a delay increasing to unacceptable levels in a design?
💡 Hint: Consider the setup and hold times in relation to delay measurements.
