Challenge Problems
Push your limits with challenges.
Question 1
How would the overall performance of a CMOS inverter change if the pMOS transistor had a W/L ratio of 4:1 while the nMOS had a W/L ratio of 1:1? Analyze the impacts on VTC and noise margins.
💡 Hint: Consider how an unbalanced ratio affects symmetry and performance.
Question 2
Considering a fabrication process that inadvertently leads to an increase in the nMOSFET Vt, predict how the inverter's operation will be affected with respect to its VTC and noise margins.
💡 Hint: Think about the relationship between threshold voltage and inverter speed.
