A feedback circuit disposed across input and output terminals of an amplifier is adapted so as not inject DC current back into the input terminal of the amplifier. The feedback circuit includes, in part, first and second current sources, a transistor, and a resistive load. The first current source supplies current to one of the terminals of the transistor in communication with an input terminal of the amplifier. The second current source receives this current and diverts it to a voltage supply. The transistor is maintained in the active region of operation. The resistive load has a first terminal in communication with an output terminal of the amplifier and a second terminal in communication with the transistor. The DC voltages at the two terminals of the resistive load are substantially equal so as to inhibit DC current flow therethrough.
