Field-effect Transistor - Advantages of FET

Advantages of FET

The main advantage of the FET is its high input resistance, on the order of 100M ohms or more. Thus, it is a voltage-controlled device, and shows a high degree of isolation between input and output. It is a unipolar device, depending only upon majority current flow. It is less noisy and is thus found in FM tuners for quiet reception. It is relatively immune to radiation. It exhibits no offset voltage at zero drain current and hence makes an excellent signal chopper. It typically has better thermal stability than a BJT.

Famous quotes containing the words advantages of, advantages and/or fet:

    Can you conceive what it is to native-born American women citizens, accustomed to the advantages of our schools, our churches and the mingling of our social life, to ask over and over again for so simple a thing as that “we, the people,” should mean women as well as men; that our Constitution should mean exactly what it says?
    Mary F. Eastman, U.S. suffragist. As quoted in History of Woman Suffrage, vol. 4 ch. 5, by Susan B. Anthony and Ida Husted Harper (1902)

    [T]here is no Part of the World where Servants have those Privileges and Advantages as in England: They have no where else such plentiful Diet, large Wages, or indulgent Liberty: There is no place wherein they labour less, and yet where they are so little respectful, more wasteful, more negligent, or where they so frequently change their Masters.
    Richard Steele (1672–1729)

    Half-opening her lips to the frost’s morning sigh, how strangely the rose has smiled on a swift-fleeting day of September!
    How audacious it is to advance in stately manner before the blue-tit fluttering in the shrubs that have long lost their leaves, like a queen with the spring’s greeting on her lips;
    to bloom with steadfast hope that, parted from the cold flower-bed, she may be the last to cling, intoxicated, to a young hostess’s breast.
    —Afanasi Fet (1820–1892)
