The voltage gain of a two-stage feedback amplifier is given by

A = ( rf / re )+1
​

How does one arrive at this relation?plz... Can someone provide me the complete derivation for this one???

Are you talking about an op-amp or discrete transistors?

 

Its for a CE transistor.

 

It would help if you would post a schematic.
