BJTs and FETs are two different kinds of transistors and also known as active semiconductor devices. … The major difference between BJT and FET is that in a field-effect transistor only majority charge carries flows, whereas in BJT both majority and minority charge carriers flow.

What is the difference and similarity between the BJT and FET?
A BJT or FET both shares the same category of transistors. These transistors have the property of both conduction as well as insulation. BJT, as well as FET, consists of three basic terminals in it….Comparison between BJT and FET.

What is the main difference between BJT and JFET?
JFET is better thermal stability but BJT is less thermal stability. JFET is a high input impedance, BJT is a low input impedance. JFET has a high current gain, BJT has a low current gain.
What are the differences between Transistor and FET?
Differences between a FET and a Bipolar Transistor
Field Effect Transistor (FET) | Bipolar Junction Transistor (BJT) | |
---|---|---|
1 | Low voltage gain | High voltage gain |
2 | High current gain | Low current gain |
3 | Very input impedance | Low input impedance |
4 | High output impedance | Low output impedance |
What is difference between BJT and FET draw and explain the basic construction of N channel JFET?
The main difference between the JFET and a BJT device is that when the JFET junction is reverse-biased the Gate current is practically zero, whereas the Base current of the BJT is always some value greater than zero.
What is the difference between FET and a BJT Why would you select a BJT over a FET or vice versa justify your answers?
FETs are voltage-controlled. They only require voltage applied to the gate to turn the FET either on or off. They do not require a biasing current for operation. BJTs offer smaller input impedances, meaning they draw more current from the power circuit feeding it, which can cause loading of the circuit.
What is difference between FET and MOSFET?
A FET works on the principle of a gate terminal changing the resistance between two other terminals (the source and drain) of the device based on a change in the field under the gate. A MOSFET is a metal oxide field effect transistor. The MOS describes the gate configuration.
Why BJT is better than FET?
It is a high input impedance device about 100 MOhm and above. FET has no offset voltage when used as switch unlike BJT. FET is relatively immune to radiation but BJT is very sensitive….FET.
