The power MOSFET device is a___________?
Correct answer: B. Voltage controlled unipolar device
- A. Current controlled unipolar device
- B. Voltage controlled unipolar device
- C. Current controlled bipolar device
- D. Voltage controlled bipolar device
Explanation
A power MOSFET is controlled by gate-to-source voltage and conducts through one type of majority carrier, making it both voltage-controlled and unipolar. Bipolar devices require carrier injection and are not the usual MOSFET classification.
