The use of cold FET measurements solves the problem
of junction heating and ANA protection. By 'cold', it is
meant that either Vgs = 0 or Vds = 0, and so a zero DC
drain current flows. Under these conditions, destructive
oscillations are prevented. Also, with the heat dissipation
equal to zero, the entire device merely has to be maintained
at the required measurement temperature. A disadvantage
of cold FET measurements is that the device is
measured under voltage and current conditions far
removed from those under which it will operate. Information
about the device is therefore lost. For example, some
nonlinear elements within a MOSFET show a current
dependence, which cannot be determined from cold
measurements.
The design of monolithic microwave integrated circuits (MMIC) is dependent on the ability to generate accurate device
models. Prior knowledge of the external parasitic components is required to determine the small-signal model of the intrinsic
device. In this report, we describe a technique and its implementation for extracting external device parasitics. The term cold
field-effect transistor (FET) refers to measurements taken when the drain is at the same voltage as the source.

What types of transistors are the following - BJT PCT UJT SBT FET GJT AJT DFT?
The BJT is the bipolar junction transistor, the PCT is the point contact transistor, the UJT is the uni-junction transistor, the SBT is the surface barrier transistor, the FET is the field effect transistor, the GJT is the grown-junction transistor, the AJT is the alloy-junction transistor, and the DFT is the drift field-junction transistor.
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.
Why is MOSFET called IGFET?
MOSFET is Metal Oxide Semiconductor Field Effect Transistor. IGFET Insulated Gate Field Effect Transistor. But these expressions are practically synonyms.
What are FETs?
Field Effect Transistor A: basically a silicon bar where the conduction is controlled by a field since there is no connection to the gate the impedance is very high
What is mean BFW11?
Its a Transistor used in JFET (Junction Field Effect Transistor)
Where was the transistor created?
The transistor was created by researchers at the university of Geneva. "The first patent for a field-effect transistor principle was filed in Canada... 1925. In 1934 German physicist Dr. Oskar Heil patented another field-effect transistor."
What is offset voltage of Field Effect Transistor?
0.7V
How many types of field effect transistor?
There are two types of field effect transistors:junction field effect transistors andmetal-oxide semiconductor field effect transistors.
What is the difference between a bipolar transistor and a field effect transistor?
A bipolar transistor uses both majority and minority charge carriers for conduction, while a field effect transistor primarily relies on majority charge carriers. Field effect transistors have a higher input impedance compared to bipolar transistors. Additionally, bipolar transistors are current-operated devices, while field effect transistors are voltage-operated devices.

Thermionic valve
Why do you bias a field effect transistor?
we do bias field effect transistor because FET works if its Q point lies into active reason .If we bias FET ,the Q point lies in active reason
