Question

We conducted an experiment for transistor bias circuits using different beta () values.

The experiment showed that some biasing schemes are more robust against the variations in beta values while other biasing schemes are easily affected by the variation. You will explain the reason.

Select two representative biasing schemes (i.e., one for each of the above cases, respectively), and explain the reason by comparing the biasing schemes in terms of their formulas for collector current, I_C and beta ().
