Q.) For Colpitts oscillator, the capacitors C1 and C2 in the feedback network are 1 µF and 25 µF respectively. Then the β value of the transistor is:

(A) 35

(B) 000.76

(D) 0.0025

Correct answer : Option (C) - 25

Explanation:

 β for a transistor is defined as the ratio of transconductance of the transistor to the input admittance, which is equal to the ratio of c2/c1. substituting the given values, β of the transistor is 25.
