What is the difference between single stage and multi stage amplifiers?
single stage amplifier contain only one stage transistor amplifier but multi stage contain more than one amplifier stage
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
What is advantage and disadvantages of multistage amplifier?
A multistage amplifier is composed of several single stage amplifiers.
What is the advantage of two stage amplifier compared to single stage?
In a two stage amplifier the gain (ratio of the output to the input quantity) of the first stage is amplified again in the second stage so the gain of a two stage amp is the product of the gain of two individual stages which is sufficient enough to drive the output device as compared to a single stage amplifier.
What is the function of resistor in single stage amplifier?
A simple, 1 transistor single stage amplifier can be made using several resistors to bias a NPN or PNP transistor into its' linear operating region. With this done, a small voltage signal applied to the input of the amplifier will have the voltage amplified at the output in a linear fashion. I'm not sure what your question is; if this does not answer it let me know.
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.
May power amplifier a voltage amplifier?
A power amplifier may also boost voltage; in audio equipment, power amplifiers often have a dial on the front that is used to control the input voltage gain. A simple power amplifier is composed of a single transistor; this type of configuration cannot provide voltage amplification as well. A voltage amplifier stage is needed. So the above example of an audio power amplifier is actually a voltage amplifier stage, followed by one or more power amplifier stages.
Why is differential amplifier preferred over single ended amplifier?
The input stage of an op amp is usually a differential amplifier; this is due to the qualities that are desirable in an op amp that match qualities in a differential amplifier: common noise rejection ratio; low input impedance, high output impedance, etc. The use of differential amplifiers in op-amps is to increase the input range and to eliminate common entries like noise.
How is negative feedback achieved in a single stage transistor amplifier?
A: Feedback is a signal fed back from the output like from collector to the base .
What is the figure of merit of 2-stage amplifier if each stage amplifier contains 10dB gain?
this site has not given the answer of my question
Distinguish between op amp and differential amplifier?
Look up "op amp" on wikipedia, there is a good drawing near the bottom right. An op amp contains a differential amplifier as the first stage, but has multiple following stages that provide amplifier near ideal characteristics of high input resistance and low output resistance (it can drive more current than a single dif amplifier stage).
Why the single stage common emitter transistor amplifier is famous and widely used in most of the application?
because of low cost and gain is high well amplified
