I have this circuit to solve:
with \$R_2=R_3\$ and \$R_4=R_5\$. I want to find the transfer function between \$I_{\text{out}}\$ and \$V_{\text{in}}\$ (differential).
I'm trying to use superposition, but the math is very long. Do you have any other idea on how to solve it?
Any hint?
I've divided \$V_{\text{in}}\$ in \$V_1\$ and \$V_2\$, and tried superposition. I've found the current on \$R_2\$ and \$R_4\$, but I'm having a problem finding out a relation between \$V_{\text{x}}\$ and \$I_{\text{out}}\$ in order to solve the system.
