Video Solutions for GATE 1993 ECE : Five Mark Questions ( Electron Devices )

1. The reverse saturation current of the collector base junction 

    (I_CBO) of a BJT is found to be 10 nA at low collector voltages. 

    The low current amplification factor (α) is 0.98. Find out the 

    change in collector current with its base open (I_CEO) when the 

    collector voltage is increased such that α increases by the 1.0%.
