Question

In field effect device if it is enhanced MOSFET for region \(V_{GS} \lt V_T\) it corresponds to region

• A. constant current
• B. enhancement
• C. depletion
• D. saturation

Hint:

If \(V_{GS} \lt V_T\), MOSFET is OFF.

Answer 1

The Correct Option is C

Concept: MOSFET regions depend on gate voltage \(V_{GS}\).

Step 1: Threshold voltage \(V_T\) is minimum voltage to create channel.

Step 2: Condition \(V_{GS} \lt V_T\) No channel formation.

Step 3: Device state MOSFET is OFF (cut-off region).

Step 4: Interpretation This is equivalent to depletion region behavior.

Step 5: Conclusion \[ \boxed{\text{Depletion region}} \]

Final Answer: \[ \boxed{(C)} \]
