Challenge Problems

Push your limits with challenges.

Question 1

You designed a NAND gate and measured a tpLH of 50 ns and tpHL of 70 ns. How do you evaluate whether these delays are acceptable for a high-speed application?

💡 Hint: Evaluate the circuitry that will use this gate and its performance requirements.

Question 2

Based on what you know about the impact of parasitic capacitance, how does the layout design influence the propagation delays of your NAND gate?

💡 Hint: Consider trace lengths and the relationship between capacitance and signal speed.
