Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Evaluate the impact of a reduction in channel length and width by 10% on a hypothetical CMOS amplifier's gain. What steps would you recommend for optimization?

💡 Hint: Reflect on how changes in geometry affect performance.

Challenge 2 Hard

A system uses multiple transistors with varying channel lengths. Calculate how a mismatch of 5% in lengths affects the overall current output if the design relies on consistent current.

💡 Hint: Consider how small variations amplify through the circuit.
