Question
(a) Draw and explain CB transistor characteristics and explain different regions of operation,. Discuss the effects of "early effect" on the output characteristics.
(b) Prove that $I_C = \beta\text{ }I_B + I_{CEO}$ for CE configuration, where symbols have their usual meanings. The reverse saturation, current CB, npn transistor is $12.5\text{ }\mu\text{A}$, $I_E = 4\text{ mA}$, $I_C = 2.96\text{ mA}$. Find $I_B$, CE current gain, $I_{CEO}$, CE collector current.
