I am trying to figure out how Razavi in his book got the following expression for Closed loop gain of a fully diff. amplifier. The circuit schematic and the equation are below.
I have come across this explanation of the calculation of the feedback factor of an inverting amplifier. This is the first time I am seeing the factor "k" being mentioned in the closed loop voltage gain.

is there any book which talks about this?

NVM, after looking at this link https://electronics.stackexchange.com/questions/330638/beta-of-inverting-opamp-amplifier
I figured out how he got the expression.
Am I right about the taylor series approximation though? It is taken when x <<< 1?
