Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given a CMOS inverter with measured VOH = 1.7V, VOL = 0.2V, VIL = 1.0V, VIH = 0.7V, compute NML and NMH. Discuss what might be the implications of these values.

💡 Hint: Focus on the formulas for noise margins.

Challenge 2 Hard

If the W/L ratio of the nMOS increases drastically while keeping that of the pMOS constant, discuss the expected changes in the VTC curve and how it might affect circuit functionality.

💡 Hint: Consider the balance when varying transistor strengths.
