Hi,

I attach an Op Amp circuit which I want to find Vo/Vi. I found the expression for Vo/Vi by using KCL, but I would like to know what alternative method of circuit analysis I could use to find Vo/Vi, that is, not use KCL directly.

NOTE: No way I'm asking for the whole solution of this. I just want suggestions so I can start doing it by myself.

Thank you.

 

It's just a circuit. You can use any reasonable technique, such as mesh current analysis.
