Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A MOSFET is operating with a V_{GS} of 3V, a threshold voltage of 1V, μ_n is 400 cm²/V·s, and C_{ox} is 1.5 fF/μm². Given W/L = 12, calculate the transconductance.

💡 Hint: Break down the components of the equation and substitute values step-wise.

Challenge 2 Hard

If a designer wants to significantly increase the transconductance without changing the voltage, how can they adjust the device parameters?

💡 Hint: Think about how these changes will affect the ratio.
