Abstract:
1. An apparatus including a substrate with interface electrodes and integrated calibration and differential signal receiver circuitry mutually coupled via a plurality of conductors, comprising: a substrate; first and second calibration electrodes disposed on said substrate to convey a calibration current and a related calibration voltage; first and second calibration conductors disposed on said substrate and coupled to said first and second interface electrodes to conduct said calibration current; third and fourth calibration conductors disposed on said substrate and coupled to said first and second calibration electrodes to convey said calibration voltage; a fifth calibration conductor disposed on said substrate and to be coupled to one of said first and second calibration electrodes and conduct said calibration current; first and second signal electrodes disposed on said substrate to convey a differential signal having a signal voltage and a signal current; first and second signal conductors disposed on said substrate and coupled to said first and second signal electrodes to conduct said signal current; third and fourth signal conductors disposed on said substrate and coupled to said first and second signal electrodes to convey said signal voltage; and integrated calibration and differential signal receiver circuitry coupled to said first, second, third, fourth and fifth calibration conductors and said first, second, third and fourth signal conductors, and including
