  • Patent number: 10605767
    Abstract: A high data rate integrated circuit, such as an integrated circuit including a large sensor array, may be implemented using clock multipliers in individual power domains, coupled to sets of transmitters, including a transmitter pair configuration. Reference clock distribution circuitry on the integrated circuit distributes a relatively low speed reference clock. In a transmitter pair configuration, each pair comprises a first transmitter and a second transmitter in a transmitter power domain. Also, each pair of transmitters includes a clock multiplier connected to the reference clock distribution circuitry, and disposed between the first and second transmitters, which produces a local transmit clock.

  • Patent number: 10513922
    Abstract: Methods and systems for monitoring material loss in a downhole environment arising from corrosion and/or erosion include placing a downhole sensor in a borehole. The resistance of the downhole sensor is measured using a four-probe resistance technique in which a power source is provided at two electrodes of the downhole sensor and voltage is measured at two voltage taps. A rise in voltage over time indicates loss of conductive material on the downhole sensor. The conductive material on the downhole sensor may be formed to provide discrete voltage increases for improving reliability of material loss and/or rate of material loss resistance measurements.
