Hi, I am trying to derive the transfer function of this notch filter. I am using simple KCL and KVL equations but I don't think I have the correct loop voltage equation. The transfer function is well published online so I know what it should be, but I am struggling to see what I'm doing wrong. If anyone can offer any insight it would be greatly appreciated!!
