Previous Year Question

Which of the following is a type of Power MOSFET based on its operation mode?
  1. Saturation type
  2. Injection type
  3. Recombination type
  4. Enhancement type

Correct answer: D

Explanation

MOSFETs are classified by channel operation as enhancement-mode or depletion-mode devices. 'Enhancement type' is therefore a valid Power MOSFET operating-mode classification.
