Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Critique a CMOS inverter design that has very low noise margins. How would redesigning the W/L ratios improve performance?

💡 Hint: Consider the current drive strength balance between the transistors.

Challenge 2 Hard

If the VDD is increased while keeping the process parameters constant, what would happen to the VTC and why?

💡 Hint: Think about the relationship between power supply and output levels.
