Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

If a designer finds that NML = 0.3V and NMH = 0.5V, discuss potential design changes to improve circuit robustness.

💡 Hint: Focus on how to enhance the weaker margin.

Challenge 2 Hard

Consider an inverter with a VIL of 1.0V and a VOL of 0.4V. Calculate NML. If NML is inadequate, what could be done to improve it?

💡 Hint: Examine both input and output specifications carefully.
