Compared to bipolar junction transistor, JFET has
Compared to bipolar junction transistor, JFET has
Show Hint
JFET: high input resistance, lower gain than BJT.
Updated On: Jul 2, 2026
- lower input impedance
- high input impedance and high voltage gain
- higher voltage gain
- high input impedance and low voltage gain
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
JFET and BJT differ in input impedance and gain.
Step 1: Input impedance of JFET Very high due to reverse biased gate.
Step 2: Input impedance of BJT Comparatively low.
Step 3: Voltage gain comparison BJT has higher gain than JFET.
Step 4: Combine properties JFET → high input impedance + low gain.
Step 5: Conclusion \[ \boxed{\text{High input impedance and low voltage gain}} \]
Final Answer: \[ \boxed{(D)} \]
