Multistage Amplifier

The multistage amplifier is generally a voltage or power amplifier. The multistage amplifier has a number of single stage amplifier that are cascaded together. Since a single stage amplifier output is not useful, they are being replaced with multistage amplifiers or multistage transistor amplifiers. The multistage amplifier are used where the gain required is high or the input signal is very small such that only a single stage amplifier cannot amplify it.
