Question

write the need of multistage ​

Answer 1

Answer:

• the performance obtainable from a single-stage amplifier is often insufficient , hence several stages may be combined forming a multistage amplifier. These stages are connected in cascade, i.e. output of the first stage is connected to the input of second stage, whose output becomes input of third stage, and so on.

Answer 2

Explanation:

Write short note on multistage amplifier. If the voltage or power gain obtained from the single stage small amplifier is not sufficient for practical application, then we have to use more than one stage of amplification to achieve necessary power or voltage gain. Such an amplifier is known as multistage amplifier.
