The input impedance of a JFET is _____________that of an ordinary transistor?
Correct answer: C. more than
- A. equal to
- B. less than
- C. more than
- D. none of the above
Explanation
Because the reverse-biased JFET gate junction draws almost no current, its input impedance is much higher than that of an ordinary BJT. A BJT requires base current, which lowers its input resistance.
