Abstract
Techniques are provided which reduce common mode noise voltage in single ended signal transmission. The common mode noise voltage is generated by a noise generating current flowing through an inductance of a return path between a transmitting circuit and a receiving circuit. The common mode noise voltage may be diminished by generating a noise cancelling current which flows through the inductance in the return path in a direction opposite to the flow of the noise generating current. As a result, a magnitude of noise current flowing through the inductance is diminished. Further the transmitting circuit and receiving circuit are isolated, by using buffering, from ground plane(s) of the transmitting and/or the receiving circuits so that such circuits are substantially unaffected by this common mode noise suppression technique.
