Question

The depletion mode MOSFET is also known as

• A. N-type MOSFET
• B. P-type MOSFET
• C. Normally-on MOSFET
• D. Normally-off MOSFET

Hint:

Depletion MOSFETs are “normally on” and require reverse bias to turn off.

Answer 1

The Correct Option is C

Depletion mode MOSFET conducts current even when gate-to-source voltage is zero. It requires a negative gate voltage (for NMOS) to turn OFF. Thus, it is called a “Normally-on” MOSFET.
