However the amplifier factor(G) decreases much faster than the gain coefficient(g). The amplifier BW A is defined as the FWHM of G( ) 0.5 ln( /2) ln2 o A g G where g is the gain BW, and Go = exp(goL). The amplifier BW is smaller than the gain BW. The difference depends on the amplifier gain characteristics. If Go = 10, Ag0.656 12
An inline amplifier is used to restore (regenerate) the optical signal to its original power level. An optical pre-amplifier is used at the end of the optical fiber link in order to increase the sensitivity of an optical receiver.

Class A power amplifier •If the collector current flows at all times during the full cycle of the signal, the power amplifier is known as class A power amplifier. •If the Q point is placed near the centre a/the linear region a/the dynamic curve, class A operation results. Because the transistor will conduct for
Amplifier Efficiency. The ideal amplifier would be 100 efficient. The lower the Q-point position on the dc load line, the higher its efficiency. Class A is the least efficient. Class C is the most efficient. 3 The AC Load Line. AC load line A graph of all possible combinations of ic and vce for a given amplifier.

Rev.0, 10/08, WK Page 1 of 5 MT-061 TUTORIAL Instrumentation Amplifier (In-Amp) Basics . Probably the most popular among all of the specialty amplifiers is the instrumentation amplifier (hereafter called simply an in-amp).The in-amp is widely used in many industrial and
microvolts. An RF amplifier is not needed. The RF amplifier provides sufficient gain for the incoming RF signal to overcome the noise floor of the mixer. The noise floor of the mixer is the noise power level, in …
The feedback-amplifier can be defined as an amplifier which has feedback lane that exists between o/p to input. In this type of amplifier, feedback is the limitation which calculates the sum of feedback given in the following amplifier. The feedback factor is the ratio of the feedback signal and the input signal.

DC Amplifier. This type of amplifier can be used for both DC (direct current) signals as well as AC (alternating current) signals. The DC amplifier’s frequency response is the same as LPF (low pass filter).The direct current amplification can be achievable only by using this amplifier, therefore later it turns into the basic building block of the differential as well as operational amplifier.

One way to describe an amplifier is by the type of signal it is designed to amplify. This usually refers to a band of frequencies that the amplifier will handle, or in some cases, the function that they perform within an electronic system. A.F.
