Q. |
The expression for IC in the compensation for instability due to ICO variation |
A. | βi+βio+βico |
B. | βi+βio |
C. | βio+βico |
D. | βi+βico |
Answer» A. βi+βio+βico | |
Explanation: in this method, diode is used for the compensation in variation of ico. the diode used is of the same material and type as that of transistor. hence, the reverse saturation current io of the diode will increase with temperature at the same rate as the transistor collector saturation current ico. |
