i want know why this circuit is not working at all. i am trying to remove dc from signal( which has dc in terms of volts and ac in terms of mill volts) and i need to amplify ac signal. my assumption is that only dc is available for certain interval of time, so i will charge capacitor. After changing input some ac will be added to dc . so i tried to subtract with opamp and amplify ac as my interest is on ac.
Suggest me what to do?
