Difference Between BJT and FET
JFET can operate in how many modes .
JFET can operate in depletion mode .
In how many regions MOSFET operates.
MOSFET operates in three regions that are Cut off Region , Triode Region , Saturation Region .
In how many modes MOSFET works.
In two modes : Depletion and enhancement modes
Why BJT is called current control device.
BJT is called current control device because input current is responsible for the amount of output current.
How many type of MOSFET are there
There are two types of MOSFET NMOS and PMOS
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.
