A wideband amplifier is an electronic circuit providing constant amplification with a ratio of its low corner frequency to its high corner frequency of more than an octave.
The widwband amplifier is complementary in concept to "audio amplifier" (20Hz-20KHz) and "video amplifier" (15KHz to 4.8MHZ).
The "opposite" concept is the narrow-band or tuned amplifier.
There's a new wideband amplifier technology called PowerBand from TriQuint Semiconductor.

Darlington amplifier has more gain when compared to cascade amplifier .
current series feedback amplifier=series parallel feedback amplifier or voltage to current amplifier,or TRANS CONDUCTANCE AMPLIFIER.
Selective amplifier is an RF amplifier which selects particular frequency and amplifier so it can operate at fixed frequency.
what is a mosfet amplifier
audio amplifier
It is a normal amplifier, fast enough to amplify high frequency video signals. The word "video" means wideband. That's why a video amplifier is used for, for instance, for t.v. signals and in wideband measuring equipment.
Usually to amplify the video signal across long distances of cable. This is necessary to maintain quality and consistency of the video signal in runs of 100 ft. or more. The word "video" means wideband. A video amplifier is used for any wideband signal.

Wideband Code Division Multiple Access
It stands for Wideband Code Division Multiple Access
The terms "wideband" and "broadband" mean the same thing. It simply means that a signal or noise or channel has a wide bandwidth. Speed is the simple answer to the difference between broadband internet access and wideband internet access, but it is really more than that. Wideband is a fairly new level of high speed internet access that allows much smoother video streaming and gaming interaction via the internet. TimeWarner has introduced it for residential customers in New York City.
A system is wideband when the bandwidth it uses covers a wide range of frequencies. Having a wide range of frequencies available allows one to transmit information on all of them thus allowing great bandwidth.
