Advantages of BJT and FET
Following are the some of the advantages of BJT and FET :
Advantages of BJT
- BJT have high current gain.
- BJT can operate in any power device .
- Gain bandwidth is large in BJT.
- In high frequency BJT perform very well.
- BJT have low forward voltage and better voltage gain .
Advantage of FET
- FET have high input impedance.
- It produce less noise.
- It is less sensitive to radiations.
- Higher operating frequency range.
- It is fabricated in less chip area.
Difference Between BJT and FET
The transistor is a three-terminal semiconductor device, it is an active device that is used in most of the electronics devices. Transistors can be used as insulators and as conductors as needed. we can use a transistor as a switch and as an amplifier. It can be used with other circuit elements and can be able to amplify current and voltage. We can classify transistors into two types that is Bipolar, and Field Effect Transistor.
BJT is a three-terminal device, it has two PN junctions. It is mostly used analog electronic device because of its high current gain. FET is a very important component in today’s electronic devices. FET is a type of device in which electric fields are used to control the flow of charges or current flowing through a channel. Due to its high input impedance, low output impedance, and high gain capacity, they are widely used in electronic devices.
BJT and FET both are used in many different devices and they have many different characteristics that make them different from each other. In this article, we will go through all the things that make them different and we will get the overview of BJT and FET.
