Be sure to use an opamp with rail-to-rail inputs and outputs if you're trying to operate from a single supply. | |

After reading the link and some more reading off the internet, i used a diode and a capacitor in place of R9. It seems i have used a very primitive detector circuit and the results are not satisfying. Do you have any suggestions ? Could you post an image or something as suggestion. I am having a bit of a hard time trying to constituting an op amp based peak detector in the feedback loop. Thank you very much :) | |
