FETs are unipolar transistors as they involve single-carrier-type operation.

JFET – Wikipedia

Thus, it is a voltage-controlled device, and shows a high degree of isolation between input and output. It is a bfw110 device, depending only upon majority current flow.

It is less noisy. It is relatively immune to radiation.

BFW10 – N-Channel JFET

It exhibits no offset voltage at zero drain current and hence makes an excellent signal chopper. It typically has better thermal stability than a bipolar junction transistor BJT. Trasconductance is an expression of the performance of a bipolar transistor or field-effect transistor FET. In general, the larger the transconductance figure for a device, the greater the gain amplification it is capable of delivering, when all other factors are held constant.


The symbol for transconductance is gm.

Semiconductor: BFW10 (BFW 10) – N-FET 30V / 20mA…

The unit is thesiemens, the same unit that is used for direct-current DC conductance. It has a relatively low gain-bandwidth product compared to a BJT.

The MOSFET has a drawback of being very susceptible to overload voltages, thus requiring special handling during installation. The fragile insulating layer of the MOSFET between the gate and channel makes it vulnerable to electrostatic damage during handling.

This is not usually a problem after the device has been installed in a properly designed circuit. Each 3 Bread board 1 One No. Pin assignment of FET: Top View Bottom View Operation: The circuit diagram for studying drain and transfer characteristics is shown in the figure1. Connect the circuit as bf1w0 in the figure1. Varying V DD in steps of 0. Drain Resistance r d: It is given by the ratio of small change in drain to source voltage V DS to the corresponding change in gate to source voltage V GS for a constant drain current I D.

While performing the experiment do not exceed the ratings of the FET. This may lead to damage of FET. Connect voltmeter and ammeter with correct polarities btw10 shown in the circuit diagram.


Do not switch ON the power supply unless the circuit connections are checked as per the circuit diagram. Properly identify the Source, Drain and Gate terminals of the transistor.

Drain and Transfer characteristics of a FET are studied. Why FET is called a Unipolar device? What are the advantages of FET? It typically has better thermal stability than a bipolar junction transistor BJT 3.

What are the disadvantages of FET? Why an input characteristic of FET is not drawn? What is the importance of high input impedance?
