The input impedance of a MOSFET is of the order of______________?
Correct answer: D. several MO
- A. O
- B. a few hundred O
- C. kO
- D. several MO
Explanation
The MOSFET gate is insulated by an oxide layer, so its dc gate current is nearly zero and its input impedance is extremely high, commonly several megohms or more.
