Determine α and β for the transistor of Example 3.1 if leakage currents (flow due to holes) are negligible and the described charge flow is constant.

Question

Determine [latex]α[/latex] and [latex]β[/latex] for the transistor of Example 3.1 if leakage currents (flow due to holes) are negligible and the described charge flow is constant.

Accepted Answer

If we assume [latex]I_{CBO} = I_{CEO} = 0[/latex], then

[latex]α = \frac{i_C}{i_E} = \frac{i_E - i_B}{i_E} = \frac{1.602 - 0.016}{1.602} = 0.99[/latex]

and [latex]β = \frac{i_C}{i_B} = \frac{i_E - i_B}{i_B} = \frac{1.602 - 0.016}{0.016} = 99.125[/latex]
