A certain common-source JFET has a voltage gain of 10. If the source bypass capacitor is removed, ______________?
Correct answer: C. the voltage gain will decrease
- A. the voltage gain will increase
- B. the transconductance will increase
- C. the voltage gain will decrease
- D. the Q-point will shift
Explanation
Removing the source bypass capacitor introduces source degeneration through the source resistor, reducing the AC voltage gain. It does not significantly shift the DC Q-point because the capacitor is open for DC in either case.
