Which of the following amplifier circuit using junction transistor has the best gain?
Correct answer: B. Common emitter
- A. Common base
- B. Common emitter
- C. Common collector
- D. All have the same gain
Explanation
The common-emitter configuration provides both substantial voltage gain and current gain, so its power gain is generally the highest of the three basic transistor configurations. Common-base has current gain near unity, while common-collector has voltage gain near unity.
