Who is more gain amplifier cascaded amplifier or darlington amplifier?
Darlington amplifier has more gain when compared to cascade amplifier .
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..................
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.
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 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..................
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
How an operational amplifier can amplify DC signals?
It takes the difference between of two input and amplify by the open loop gain of the amplifier or closed loop gain of the amplifier. It is very hard to control open loop gain of 100 Db so it very seldom used
Why does a CE amplifier have a high gain?
GAIN is a function of load current but basically a small current in the base will make a big change of collector current therefore making a transistor a voltage amplifier as opposed to a current amplifier
Why is a common collector used in the last stage of the amplifier?
becoz it gives good gain which is necessary for an amplifier.
