Detailed Solution
Download Solution PDFThe modes of operation of an NPN transistor are as follow:
|
Emitter-base junction |
Collector-Base junction |
Mode |
|
Reverse bias |
Reverse bias |
Cutoff |
|
Reverse bias |
Forward bias |
Reverse active |
|
Forward bias |
Reverse bias |
Active |
|
Forward bias |
Forward bias |
Saturation |
From the above table, we can conclude that for normal operation (active mode) of NPN transistor, emitter-base Junction must be forward biased and base-collector junction must be reverse biased.
