The disadvantage of base resistor method of transistor biasing is that it_________________?
Correct answer: B. Is sensitive to changes in ß
- A. Is complicated
- B. Is sensitive to changes in ß
- C. Provides high stability
- D. None of the above
Explanation
In base-resistor bias, the collector current depends strongly on beta through IC approximately equal to beta times IB. Since beta varies between transistors and with temperature, the operating point is poorly stabilised.
