Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

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.

Challenge 2 Hard

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.
