Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

If an inverter has Vth=0.6V, VOH=1.8V, and VOL=0V, compute NML and NMH, and discuss how modifying W/L ratios could affect these values.

💡 Hint: Apply the formulas for noise margins and consider the transistor strengths.

Challenge 2 Hard

Design an inverter that achieves a noise margin of at least 0.3V for both logic levels. Specify the W/L ratios for balanced drive strengths.

💡 Hint: Experiment with various ratios while confirming requirements for VIL, VOL, VIH, VOH.
