Question 1
What is the impact of increasing the nMOS W/L ratio?
- It decreases VOH
- It increases VOL
- It improves NMH
- It affects Vth
💡 Hint: Consider how the ratios shift transistor outputs.
Question 2
True or False: A well-balanced W/L ratio between nMOS and pMOS leads to a VTC closer to VDD/2.
- True
- False
💡 Hint: Reflect on the target performance of an inverter.

Challenge Problems
Push your limits with challenges.
Question 1
Given that a specific nMOS has a Vth of 1.2V and you need to decrease it to improve symmetry in a CMOS inverter design, what adjustments to the W/L ratio could you consider making?
💡 Hint: Think about how changes in width affect threshold levels.
Question 2
You have designed a CMOS inverter but find that NMH is less than NML. How would you address this issue based on your knowledge of W/L ratios?
💡 Hint: Consider the balance needed for optimal noise margins.
