Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A CMOS inverter operates with a 1.8V supply and drives a load of 150 fF. If it switches at 15 MHz with an activity factor of 1, calculate the dynamic power dissipation.

💡 Hint: Apply the formula carefully with the given values.

Challenge 2 Hard

Discuss how you would optimize a CMOS inverter to reduce both static and dynamic power dissipation without compromising performance.

💡 Hint: Consider methods that align with design principles in modern VLSI.
