    Hi Guys. I need your help.

    In the attached file "amp.jpg" you will see a circuit. Suppose that R4/R3 =R2*(1−ε)/R1.

    How to show that the differential mode gain and the common mode are those in the attached figure "re.jpg"?

    Thank you so much in advance

    Is this a homework problem? If so, it belongs in the homework help forum, and you would need to show some effort to solve it.
