Biasing is used in transition amplifiers to
1. Stabilize the operating point against temperature variations.
2. Place the operating point in the linear region of the characteristics.
3. Make α, β and ICO of the transistor independent of temperature variations.
4. Reduce distortion and increase dynamic range.
  • a)
    1, 2, 3 and 4
  • b)
    1, 2 and 4 only
  • c)
    1, 2 and 3 only
  • d)
    2, 3 and 4 only
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
Biasing is used in transition amplifiers to1. Stabilize the operating ...
The purpose of Biasing in BJT amplifier:
i) To Stabilize Q-point in its linear region of operation (Q-point is an operating point).
[Statement 2 correct]
ii) To stabilize Q-point in against variation of temperature because
Ic = βIB + (1 + β) Ico
Ico → leakage current.
Where Ico, β1, and IB are temperature dependent.
i.e. Temp ↑ → Ico ↑ → β ↑ → α ↑     
(∵β=α1−α)
[Statement 1 correct], [Statement 3 wrong]
iii) To reduce distortion and increase dynamic range.
Since biasing fixed the Q-point so that there is no variation in the output so distortion is reduced hence dynamic range i.e. operating range of the amplifier is improved.
[Statement 4 correct]
So, statement 1, 2, 4 are correct.
iv) Biasing must provide the operating point independent of β of the transistor. So that variation in β due to temperature change does not affect the Q-point of an amplifier.
