Practice Questions
Test your understanding with targeted questions related to the topic.
Question 1
Easy
What is the effect of increasing the width (W) of an n-MOSFET?
💡 Hint: Think about how wider paths allow more flow.
Question 2
Easy
Define threshold voltage (Vth) in the context of n-MOSFET.
💡 Hint: It's the 'gatekeeper' voltage.

Challenge Problems
Push your limits with challenges.
Question 1
Analyze a n-MOSFET circuit where W = 10 µm, L = 2 µm, Vth = 1V, and VGS = 3V; calculate ID in the saturation region if VDS is specified.
💡 Hint: Specify K based on given parameters.
Question 2
Sketch the I-V curve for the described n-MOSFET and label the triode and saturation regions, explaining the transition.
💡 Hint: Consider how VGS and VDS influence I.
