Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given specific load capacitance values, design a CMOS inverter where the propagation delay must not exceed 30 ps. What W/L ratios would you choose, and why?

💡 Hint: Consider how each adjustment affects the overall delay.

Challenge 2 Hard

A CMOS inverter exhibits unusually high static power consumption. Identify possible causes and suggest design adjustments to minimize it.

💡 Hint: Look into the relationship between device structure and leakage.
