Question 1
Easy
What does VOH represent in a VTC?
💡 Hint: Think about the behavior of the output when the input is low.
Question 2
Easy
Define VIL.
💡 Hint: Consider the point where the inverter still perceives the input as '0'.

Challenge Problems
Push your limits with challenges.
Question 1
Consider a CMOS inverter where VOH is 1.8V, VOL is 0V, VIL is 0.5V, and VIH is 1.5V. Calculate NML and NMH. Discuss the implications of these margins.
💡 Hint: Focus on using the definitions of noise margins.
Question 2
If the W/L ratio for the pMOS increases significantly while maintaining the nMOS constant, predict how this might affect Vth and noise margins.
💡 Hint: Think about the roles of transistor sizes in affecting inverter balance.
