A MOSFET differs from a JFET mainly because _________________?
Correct answer: C. the JFET has a pn junction
- A. of power rating
- B. the MOSFET has two gates
- C. the JFET has a pn junction
- D. none of the above
Explanation
A JFET controls its channel through a reverse-biased pn junction, whereas a MOSFET uses an insulated metal-oxide gate. Thus the presence of a pn junction is the key distinction listed.
