  • Patent number: 10274629
    Abstract: A method is provided for transmitting signals on a multi-conductor cable (12) formed from a plurality of conductors (1-7) surrounded by an armor (10), the plurality of conductors having a central conductor (7) surrounded by a first peripheral layer of conductors (1-6) with an even number of conductors symmetrically arranged around the central conductor. The two following transmission modes are carried out simultaneously: a common mode (TX1) that uses the central conductor (7) with a return on the armor (10), for transmitting a first signal (s1); and a differential mode (TX2) between a first path comprising all odd rank conductors (1,3,5) of the peripheral layer and a second path comprising all even rank conductors (2,4,6) of the peripheral layer, for transmitting a second signal (s2).

  • Patent number: 9154147
    Abstract: The present disclosure relates to the field of background estimation in a time-interleaved analog-to-digital converter (ADC). More specifically, the present disclosure relates to systems and methods for background estimation of offset and gain errors in a time-interleaved ADC based on sample count. The error estimation unit of the time-interleaved ADC system includes a counting unit, a subtractor and an integrator. The method for estimating an offset error in a time-interleaved ADC includes determining signs of the signals and outputting corresponding values by the counting unit. The values are further compared and integrated to estimate the offset error. The method for estimating a gain error in a time-interleaved ADC includes determining the absolute values of the signals and comparing the absolute values with a predetermined threshold value. The comparison results are further integrated to estimate the gain error.
