Challenge Problems
Push your limits with challenges.
Question 1
A MOSFET has W = 5 ΞΌm, L = 2 ΞΌm, with V_GS = 7 V and a V_th = 3 V. Calculate the current contribution if those conditions result in a channel operating short.
π‘ Hint: Consider whether the MOSFET is in the triode or saturation region.
Question 2
Explain the significance of designing a MOSFET to achieve a specific I_DS when connecting to a load. What factors will influence this design?
π‘ Hint: Reflect on how real-world applications require tailored designs for current versus the device specifications.
