Practice Questions

Test your understanding with targeted questions

Question 1 Easy

What happens to a MOSFET in the cutoff region?

💡 Hint: Think of the cutoff as a light switch being off.

Question 2 Easy

Define the triode region in MOSFETs.

💡 Hint: It’s like a variable resistor.

Question 1

What is the condition for a MOSFET to be in the cutoff region?

V_{GS} < V_{th}
V_{GS} > V_{th}
V_{GS} = V_{th}

💡 Hint: Think of the cutoff like a switch being off.

Question 2

True or False: In the saturation region, the drain current
I_D
remains constant regardless of
V_{DS}
.

True
False

💡 Hint: Consider how a faucet works when fully opened.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

If a specific MOSFET has a threshold voltage of 0.7V and operates under a
V_{GS} = 1.5V
and
V_{DS} = 1V
, specify the operational region. What’s the implication?

💡 Hint: Check both voltage conditions — one for gate and another for drain-source.

Challenge 2 Hard

Consider MOSFETs in digital circuits usually operate in cutoff and saturation. Why are these ideal regions for such applications?

💡 Hint: Think about how the on/off states relate to digital information.
