Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

You are tasked with designing a CMOS inverter with specific parameters. If you choose W/L ratios of 1/2 for nMOS and 2/1 for pMOS, discuss how this will impact the VTC. What are the potential drawbacks?

💡 Hint: Think about the relationship between size and performance based on mobility.

Challenge 2 Hard

Given a scenario where you want a balanced noise margin for your CMOS inverter with VDD at 3V, outline your approach to determining the necessary W/L ratios.

💡 Hint: Use VTC analysis to guide your adjustments.
