For a BJT , the common-base current gain alpha=0.98and the collectorbase junction reverse bias saturation I_(CO) = 0.6muA . This BJT is connected in the commone emitter mode and operated in the active region with a base drive current I_(B) =20muA . The collector current I_(C) for this of operating is . |

Answer» SOLUTION :`alpha=0.98` and `I_Co=0.6 muA`. Collector CURRENT `I_C=betaI_B+(1+beta)I_(Co)` `beta(alpha)/(1-alpha)=(0.98)/(1-0.98)=49` THUS, `I_C=(49xx20)+(50xx0.6)=980+30=1010muA` `I_C=1.01muA` |
