## Homework Statement

The problem ask me to write the transfert function of a electrical circuit witch include an operational amplifier. I've follow some instruction bur I cannot figure out from this problem.

Could you suggest me somethings?

I'd like to calculate G(S) = U(s) / Y(s)

where U(s) is Lasplace transform of u(t) and Y(s) is Lasplace transform of y(t)

The circuit, and solution is in attached file tf.pdf.

I start cualculating the equivalent impedance Z2.

I get: R + 1/SC

How can I write equivalent impedance for Z1.

I'd like to apply the formula:

G(s) = U(s)/Y(s) = -Z2/Z1

Thank you very much!
