  • Patent number: 9094076
    Abstract: Aspects of a method and system for interference cancellation substantially as shown in and/or described in connection with at least one of the figures, as set forth more completely in the claims. In this regard, a receiver may be operable to receive a differential signal via a differential channel, and to sense a common mode signal on the differential channel. A frequency range in which interference is present in the common mode signal may be determined. The differential signal and the common mode signal may be filtered to attenuate frequencies outside the determined frequency range. A phase and/or amplitude of the filtered common mode signal may be adjusted based on the filtered differential signal and the adjusted and filtered common mode signal may be subtracted from the received differential signal. The common mode signal may be sensed via a pair of resistors coupled to the differential channel.

  • Publication number: 20070112901
    Abstract: In one embodiment, a configurable device is provided for multiplying a plurality of digital words with a corresponding plurality of coefficients. The configurable digital filter includes: a plurality of lookup tables, each lookup table corresponding to at least one of the coefficients and operable to receive at least a portion of a corresponding at least one of the digital words, each lookup table configured multiples of the corresponding at least one coefficient such that the lookup table is operable to retrieve an entry to provide an output equaling a multiplication of the portion with the corresponding at least one coefficient.
