Why the name is FET?
FET stands for Field Effect Transistor. The name FET comes because the gate current of a field effect transistor is zero and current present in the source conductor is due to an electric field produced by the substrate material placed between the gate and the source.
When FET is invented and who invented it?
Field Effect Transistor (FET) was invented in 1926 by Julius E. Lilienfeld.
Is FET a bipolar?
no. its unipolar
What is the control electrode in a FET?
The Gate.
Which device is similar to FET?
diodes
Thermal runaway is not possible in FET because as the temperature of FET increase?
mobility decreases
Why there is no thermal runaway in fet?
in FET the conduction is due to the majority carriers. here the minority carrier conduction doesn't takes place as in BJT. hence the current flow depends only on the majority carriers . hence ther is no thermal runaway in FET.
Is it possible for me to study for senior phase teaching in fet?
Yes, it is possible for you to study Senior Phase teaching in FET. Further Education and Training offers several teaching programs for students completing their degree.
Why does your hair grow when you fet goosebumbs?
because
Advantages of fet over bjt?
mainly i will tell ttwo advantages:- 1)in FET "thermal runaway" never occurs but in bjt it occurs easily...thermal runaway means overheating and damage of fet due to different biasing voltages.. 2) since FET is a unipolar device so only one carrier type is required here ,but bjt is a bipolar device .. 3) FET is smaller in size than BJT of same rating. i mean to say that at the place of 10 bjts we can use 90 FETs ..so area cosumption is less
What is fet and parameter of fet?
explain all the parameters of fet
Why FET produces less noise than BJT?
because the fet is made out of carbon metal oxide and the bjt is made out of silicon or germanium
What is the difference between jfet and bjt?
FET's (field effect transistors) are unipolar devices because unlike BJT's that use both electron and hole current, they operate only with one type of charge carrier. BJT is a current-controlled device; that is the base current controls the amount of collector current. FET is a voltage-controlled device, where voltave between two of the terminals (gate and source) controls the current through the device. BJT's have a low input impedance ( ~1k -3k ohms), while FET's have a very high input impedance (~10^11 ohms). Consequently FET's have a lower power consumption. BJT's produce more noise than FET's . FET's have a slower switching speed . BJT's are subject to thermal runway while FET's are immune to this problem. BJT's have a higher cutoff frequencey and a higher maximum current then FET's. FET's are easy to fabricate in large scale and have higher element density the BJT's.
Why FET is called square law device?
A FET is called a square-law device because of the relationship of ID to the square of a term containing VGS.
What is Fet's population?
Fet's population is 9,485.
Why jfet called as fet?
FET is a field effect transistor, abbreviated to FET. There are two basic types of FET: a junction FET abbreviated to JFET and an insulated gate FET , abbreviated to IGFET. The most common type of IGFET is a metal-oxide silicon FET, Known as a MOSFET. Modern microprocessors may contain tens of millions of MOSFETs.
When did Fet-Mats die?
Fet-Mats died in 1677.
