For a BJT, the common-base current gain $\mathit{\alpha }=0.98$ and the collector base junction reverse bias saturation current I_CO = 0 .6 μA. This BJT is connected in the common emitter mode and operated in the active region with a base drive current I_B = 20 μA  . The collector current I_C for this mode of operation is:
