The need of multistage amplifier

The voltage (or power) gain, obtained from a single stage small signal amplifier, is limited. Therefore, it is not sufficient for all practical applications. Therefore, in order to obtain greater voltage and power gain, we have to use a „MULTISTAGE AMPLIFIER‟. 

Frequency response of R-C coupled amplifier.
