I calculate the amplitude of output signal by using the formula shown in figure. where R1 = 1 k ohm and Cf = 1 μF and Vin is sine signal. I got my answer is 5 V. Is it right? I want to know that why Rf (feed back resistor) did not contribute here while calculating V(out).
Sorry, previously I post the wrong circuit in which I showed positive feedback instead of negative feedback.
