What is bjt and jfet?
BJT is Bipolar junction transistor FET is Field effect Transistor It is a current controlled device It is voltage controlled device
What are the example current controlled device?
Bipolar junction transistor(BJT)
Why high noise in bipolar junction transistor?
In the case of Bipolar Junction Transistor current conduction is due to both holes and electrons. That's why noise is high in Bipolar Junction Transistor
What is FET?
FET is abbreviation of Field Effect Transistor. This is a transistor in which current is controlled by voltage only and no current is drawn. It is a high input impedence device and is used in computers, telecommunication and control circuits. This transistor is better in certain parameters as compared to BJT, that is Bipolar Junction Transistor.
Name the device that receives a signal and retransmit it at a higher level of higher power?
A relay or repeater. EDIT: The bipolar junction transistor
What is the center section of a transistor called?
in bipolar transistors it is called the basein field effect transistors it is called the channel
What is the meaning of N P N?
An NPN device is a bipolar transistor formed by two opposing PN junctions in close proximity.Another answerNPN indicates that the transistor has Negative Positive Negative substrates
Why ordinary transistor is known as bipolar junction transistor?
Transistor is known as bipolar junction becoz it has 2 pole. Input is given to the 2 junction and output is taken from to junction
Is junction transistor and bipolar junction transistor are same?
Yes, the are different names for the same thing.
How is mosfet different from bjt?
BJT(Bipolar junction Transistor)-It is bipolar device -meaning both electron and holes are responsible for conduction.-It is mainly used for amplification and switching purposes.-It is current controlled device.MOSFET(Metal Oxide Semiconductor Field Effect Transistor)-It is unipolar device -meaning only one of the charge carriers is responsible for conduction.-It has very high input resistance.Due to this reason it is used in initial stage of Operational amplifier.-It is voltage controlled device.
Why FET is called as a unipolar transistor?
The FET is a semiconductor device with the output current controlled by an electric field. Since the current is carried predominantly by one type of carriers, the FET is known as a unipolar transistor.
Which bipolar transistor circuit carries the lowest current?
Drain is the answer
