  • Patent number: 7840134
    Abstract: A system (50) includes a communication path (170) and transmits data on a network (103, 106). A transmitter (101) transmits data on the network and a receiver (112) receives data from the network. A component (102, 114) in the communication path has a transfer characteristic (C1, C2, C3) adjusted in response to errors in data transmitted over and received from the network in order to reduce the error rate.
    Type: Grant
    Filed: June 16, 2009
    Date of Patent: November 23, 2010
    Assignee: Broadcom Corporation

  • Patent number: 7463706
    Abstract: Aspects of the invention provide a method and system for reducing signal distortion within an on-chip transitive module. In response to receipt of a signal bearing at least one external clock frequency, at least one harmonic signal of the signal bearing the at least one external clock frequency may be generated. At least one synchronization clock frequency signal may be created from the generated at least one harmonic signal. The synchronization clock frequency signal may subsequently be supplied to at least one power source. Accordingly, the at least one power source may serve as an input power source to at least one on-chip system component of the transitive module with. In this regard, an output of the at least one power source may have at least a frequency attribute of the synchronization clock frequency signal. The synchronization clock frequency signal may reduce signal distortion produced by the at least one power source.

  • Patent number: 5786700
    Abstract: A process determines a linear interconnection resistance R between two external access points of an electronic device. The device comprises a chip, a chip carrier and wiring between the chip and carrier. The chip comprises an ESD device such as a diode which is electrically connected between the two access points. To begin the process, various currents are injected from one of the access points to another and corresponding voltages are measured across the two access points. Alternately, various voltages are applied from one access point to the other and corresponding currents are measured. The applied voltages and injected currents all forward bias the ESD device. These current-voltage relationships are applied to an interconnection model algorithm to yield the interconnection resistance.
