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:
β
Correct Answer: (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.
