Which of the following regions of transistors are, respectively, heavily dopped and lightly dopped?
- A Collector and emitter
- B Base and emitter
- C Emitter and base
- D Emitter and collector
Answer & Solution
Correct Answer
(C) Emitter and base
Step-by-step Solution
Detailed explanation
In a transistor, emitter region is highly doped because it injects charge carries toward base and collector region.
Collector region is moderately doped because in recombination of charge carriers take place in this region.
Base region are lightly doped, so that recombination of charge carriers is small.
Collector region is moderately doped because in recombination of charge carriers take place in this region.
Base region are lightly doped, so that recombination of charge carriers is small.
