A n-channel D-MOSFET with a positive VGS is operating in _______________?
Correct answer: B. the enhancement-mode
- A. the depletion-mode
- B. the enhancement-mode
- C. cut off
- D. saturation
Explanation
A positive VGS in an n-channel depletion MOSFET attracts additional electrons to the channel, enhancing its conductivity. This is enhancement-mode operation, although the device can also have a particular saturation-region bias depending on VDS.
