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 else can I help you with?
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 Bandwidth of RF amplifier?
That depends on its purpose. Some examples:RF amplifier in IF stage of AM radio: 10KHz.RF amplifier in TV set: 6MHz.RF amplifier in IF stage of FM radio: 200KHz.An RF amplifier in a military RADAR set will probably have very narrow bandwidth to reduce jamming possibility, but wide enough to allow for doppler shift of targets.
Does the power amplifier amplifies the power?
the final stage of a power amp is a current amplifier in a bipolar design and a voltage amp in a FET design.
Working of RC coupled amplifier?
In a two stage RC coupled amplifier, the two transistors are identical and a common power supply is used. The input is provided to the first stage of the amplifier where it is amplified and this output is used as input for the second stage. This is amplied once again by the other transistor in the second stage and the final output is obtained. There will be a 180 degree phase shift after the first stage amplification which is nullified by the 180 degree phase shift of the second stage amplification.Thus, we obtain an output which is an amplified signal of the input and is in phase with the input signal.
Basic theory of two stage RC coupled amplifiers?
connections are to be made per the crkt the main of this crkt is to make strong or to bost the signal comming to the crkt input is given with ac supply and they are connected to resistor and capacitor when the ac suppply is given it contains slight amount of dc supply so to block the dc supply capacitor is used and the dc supply is given at the collector so that resistor present at c and ground gets biased then another capacitor used at c to ground for removing the dc supply then out put seen on cro across collector to ground we get the perfect amplified signal the more we give the coupled amplifer the most amplfed sgnal we get
What is advantage and disadvantages of multistage amplifier?
A multistage amplifier is composed of several single stage amplifiers.
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
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.
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
What Advantages of double tuned amplifiers over single tuned amplifiers?
The primary advantage of a double tuned amplifier, such as, an amplifier with a tuned circuit on the input and the output, is narrow bandwidth. Another advantage to the circuit is impedance matching with the previous stage, etc. And last but not least your double tuned amplifier will have more gain for electrons spent getting the job done. In our battery operated everything world that is an important design factor.
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).
What is the main advantage of a multistage rocket compared to a single stage rocket?
Ah, a multistage rocket is like painting a beautiful landscape with layers of colors. The main advantage is that it can shed empty fuel tanks and engines as it goes higher, making it lighter and more efficient. Just like adding new layers of paint to a canvas, each stage propels the rocket closer to its destination.
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
Identify the simple subject in the following sentence During the rock concert an amplifier exploded on stage?
An amplifier
