What Are ‘emitter Injection Efficiency’ And ‘base Transport Factor’ And How Do They Influence The Transistor Operation?
The ratio of current of injected carriers at emitter junction to the total emitter current is called the emitter junction efficiency. The ratio of collector current to base current is known as transport factor i.e. β* = IC/IB The larger the value of emitter injection efficiency, the larger the injected carriers at emitter junction and this increases the collector current. The larger the β* value the larger the injected carriers across collector junction and hence collector current increases.
