Difference between FET(field effect transistor) and BJT(biploar junction transistor)
|
BJT |
FET |
|
It requires both holes and electrons for working of
transistor |
It requires either holes or electrons depending on
their majority |
|
It is current controlled device |
It is voltage controlled device |
|
It is more noisy than FET |
It is less nosiy due to absence of junction |
|
Works well even at high frequency |
Performance vary with the frequency |
|
For thermal stability we need to bias the BJT |
It has good thermal stability due to absence of
minority charge carriers |
|
Terminals are Emitter, Base, Collector |
Terminals are Gate ,Source ,Drain |
BJT
FET
