For transistor action, which of the following statements are correct
A. Both the emitter junction as well as the collector junction are forward biased.
B. The base region must be very thin and lightly dopped.
C. Base, emitter and collector should have same doping concentration.
D. The emitter junction is forward and collector junction is reverse bias.
Choose the correct answer from the options given below:
- A A, B and D only
- B A and D only
- C A and B only
- D B and D only
Answer & Solution
Correct Answer
(D) B and D only
Step-by-step Solution
Detailed explanation
For a transistor to operate in its active region, the base must be thin and lightly doped to minimize charge carrier recombination. Additionally, the emitter-base junction must be forward-biased to inject carriers, while the collector-base junction must be reverse-biased to…
