The purpose of emitter capacitor (i.e. capacitor across RE) is to ______________?
Correct answer: A. Avoid voltage gain drop
- A. Avoid voltage gain drop
- B. Forward bias the emitter
- C. Reduce noise in the amplifier
- D. None of the above
Explanation
The emitter capacitor bypasses the a.c. signal around RE, reducing emitter degeneration and preventing the voltage gain from falling. RE still controls d.c. bias because the capacitor is open to d.c.
