  • Patent number: 8779777
    Abstract: A current sense resistor circuit may include a primary current sense resistor that drifts with age. A secondary current sense resistor may drift with age in substantial unison with the primary current sense resistor. A calibration resistor may not drift with age in substantial unison with the primary current sense resistor. A compensation circuit may compensate for aging drift in the resistance of the primary current sense resistor based on a comparison of the calibration resistor with the secondary current sense resistor. The secondary current sense resistor may be in parallel with the primary current sense resistor, except when the compensation circuit is comparing the calibration resistor with the secondary current sense resistor.

  • Patent number: 7586430
    Abstract: The invention relates to an integrated circuit (1) which comprises a novel bidirectional mixed signal single-wire interface (6) via which the circuit receives command information from a host and transmits conditioned analog signals to the host. In order to implement the mixed signal interface, the integrated circuit is provided with means for analog signal conditioning (2), command detection (3), and digital control (4). In a preferred embodiment of the invention, current detectors are used for command detection and respond to the current flowing through the interface connection (6) so that commands can be given even when analog signals are present on the bus. The invention relates to several methods of operation, especially methods for operating a plurality of the integrated circuits on the same mixed signal bus, and methods for the compatible operation with conventional integrated circuits.

  • Patent number: 7173993
    Abstract: Method for sampling phase control for clock and data recovery of a data signal includes sampling a received data signal with a first sampling signal comprising equidistant sampling pulses, minimizing phase deviation between the first sampling signal and the phase of the received data signal to generate an adjusted second sampling signal, and sampling the received data signal with the adjusted second sampling signal to generate sampling data values. The method also includes integrating the sampling data values of the sampled data signal to form a summation value, and altering the phase of sampling pulses of the adjusted second sampling signal until the integrated summation value exceeds a threshold value that can be set.
