QUOTE(ryansxs @ Aug 10 2007, 01:14 AM) so that the all signal voltage will drop in the input of the amplifier. therefore no voltage is lost elsewhere. noob questions when I look at the internal component of an omamp, I saw that the input and output are not connected, why is it so?how are you going to amplify the signal?
