Hi, I am simulating this circuit for personal development. The gain of the integrator can be calculated using the following formula:
Gain = -Rf/R1 (1/(1+(2 x pi x f x C1 x Rf)))
But, how to calculate the gain of this circuit when diodes are introduced for rectification. I tried for some time. But couldn't get the result I see on simulation. How to calculate the gain of this circuit and output voltage(both Vrms and Vdc) with that gain?
Also, if anybody explains how this circuit works, it will be helpful for me.
