The internal gain of an amplifier is the gain or the amplification factor of the transistor used in it....................it is internal because it is fixed for transistors while manufacturing..................
Darlington amplifier has more gain when compared to cascade amplifier .
neutralization is one of the methods to make the amplifier unilateral i.e. to remove internal feedback of the amplifier. It is done to obtain the maximum gain from an amplifier.
The Gain provided by the multistage amplifier is greater than the gain of single stage amplifier. The gain of the two stage amplifier is the product of the gain of the individual stages.
A: As frequency increases all amplifier exhibits losses due to internal capacity or internal devices frequency limit. At the hi end of the frequency the amplifiers begins to loose gain gradually as a function of higher frequency that is what roll off is.
Since we know that the amplifier gain is given by A=Output voltage/input voltage (where A is the amplifier gain) So, it can be written as output voltage=A*input voltage, so when the output part increases gain increases but when input part increases gain decreases

A: As frequency increases the performance of the amplifier decreases to point where because of its internal make it reaches no gain or unity gain. Or it can be unity gain as designed like for a signal buffer

If one amplifier has its own feedback then that will be its gain witch can be added to the next amplifier gain. if both amplifier have a common feedback then that will be to total gain for both.

Current gain. At the cost of no voltage gain.
The voltage gain of an amplifier is 200. The decibel voltage gain is? Answer Gain in dB = 20 * log 200 = 46 dB
it reduces the gain
here we r going to see about the derivation of the reset gain... the instrumentation amplifier which has got two stages that is gain stage and differential stage
