In a particular technology, a small BJT operating at vBE = 28VT conducts a collector current of 100 µA. What is the corresponding saturation current?
For a transistor in the same technology but with an emitter junction that is 32 times larger, what is the saturation current?
What current will this (second) transistor conduct at vBE = 28VT ?
What is the base-emitter voltage of the latter transistor at iC = 1 mA? Assume active-mode operation in all cases.
