Hi, my question is about the input-referred noise of an opamp when I use a capacitive feedback (see picture). In different papers and books I find that there is the following relation between the noise of the opamp with and without feedback: Vnoise^2 = (Cgg(Input Transistors)+C1+Cfeedback/C1)^2*V_ota^2 That seems to be a capacitive divider somehow but I cannot derive that equation for myself... Hope someone can help me
