The transistor circuit containing more than one stage of amplification is known as Multistage Transistor Amplifier.

In a multistage amplifier, a number of single amplifiers are connected in cascade arrangement i.e. Output of first stage is connected to the input of the second stage through a suitable coupling device and so on. The purpose of coupling device (e.g a capacitor, transformer etc.) is 
(i) to transfer a.c. output of one Stage to the input of the next stage and 
(ii) to isolate the d.c. conditions of one stage from the next Stage.
