Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given a NAND gate structure with NMOS widths of 0.5um and PMOS widths of 1.0um, analyze how changing NMOS widths to 0.75um affects propagation delay and discuss why.

💡 Hint: Consider how resistance changes with width and the potential impact on loading.

Challenge 2 Hard

How would you utilize logical effort to design a faster NOR gate if your initial tests show poor performance? Propose strategies for optimizing its design.

💡 Hint: Reflect on both NMOS and PMOS configurations for optimizing speed.
