When you daisy chain two amplifiers how do you determine the combined output?
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.
What is meant by external gain of amplifier?
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..................
The voltage gran of an amplifier is 200 The decibel voltage gain is?
The voltage gain of an amplifier is 200. The decibel voltage gain is? Answer Gain in dB = 20 * log 200 = 46 dB
Why you need operational transconductance amplifier?
Usually output of an amplifier is a voltage ,...but in case of Operational Transconductance Amplifier ,Iout (current ) is the output. This feature, makes it useful for Electronic control of amplifier gain .
what is the Primary function of the common collector amplifier?
current gain
Who is more gain amplifier cascaded amplifier or darlington amplifier?
Darlington amplifier has more gain when compared to cascade amplifier .
Why Bypass capacitors used in electronic amplifier?
A: A transistor needs a bias or voltage to operate in a linear region unfortunately that is detrimental to gain so by bypassing this emitter voltage the AC gain can be improved.
Need of multistage 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.
What is internal gain of amplifier?
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..................

Why does amplifier gain reduce?
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

What are the advantages and disadvantages in using common collector amplifier?
Current gain. At the cost of no voltage gain.
The voltage gran of an amplifier is 200 The decibel voltage gain is?
The voltage gain of an amplifier is 200. The decibel voltage gain is? Answer Gain in dB = 20 * log 200 = 46 dB
What is the effect of Rs and RL on the voltage gain of an amplifier?
it reduces the gain
What is the effect of negative feedback in a noninverting amplifier?
Negative feedback in a noninverting amplifier results in improved stability and reduced drift.
Derive the gain equation of instrument amplifier?
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
