  • Publication number: 20130012016
    Abstract: A protection layer is coated or otherwise formed over the interconnect structure. The interconnect structure includes a metal line (such as top and bottom metal layers connected by a metal via) and a low-K material. The protection layer includes a vertically aligned dielectric or other material dispersed with carbon nanotubes. The protection layer could include one or multiple layers of carbon nanotubes, and the carbon nanotubes could have any suitable dispersion, alignment, and pattern in each layer of the protection layer. Among other things, the carbon nanotubes help to reduce or prevent damage to the interconnect structure, such as by reducing or preventing the collapse of the low-K material or delamination between the metal line and the low-K material.

  • Patent number: 8351614
    Abstract: The present disclosure provides a digital audio signal processing system that comprises a set of delay lines, allpass and lowpass filters to achieve the reverberation effect. The present disclosure further provides a method for generating and controlling digital reverberations for audio signals.

  • Patent number: 8351954
    Abstract: In a PBSS cluster environment, the beacon interval is allocated such that each PBSS in a PBSS cluster possesses its own master sub-beacon interval. Moreover, each member of the PBSS cluster can share unoccupied sub-beacon intervals. When a master PBSS fails to use its own master sub-beacon interval or the beacon intervals which are unoccupied, the available idle time within the beacon interval can be utilized by other member PBSSs in the PBSS cluster. As available or idle beacon interval time is allocated, each master PBSS retains the highest priority to its own master sub-beacon interval thus providing immediate access to a beacon interval when necessary.

  • Patent number: 8349710
    Abstract: Described herein are techniques for forming, during wafer processing, a conductive shielding layer for a chip formed from a wafer. The conductive shielding layer can be formed on multiple sides of a chip prior to dicing the wafer to separate the chip from the wafer. A wafer may be processed to form trenches that extend substantially through the wafer. The trenches may be formed opposite scribe lines that identify boundaries between chips of the wafer and may extend through the wafer toward the scribe lines. A shielding layer may be formed along the trenches.

  • Patent number: 8351529
    Abstract: A method (200a-200b), apparatus (104), and computer program for detecting sequences of digitally modulated symbols transmitted by multiple sources (102, 102a-102t) are provided. A real-domain representation that separately treats in-phase and quadrature components of a received vector, channel gains, and a transmitted vector transmitted by the multiple sources (102, 102a-102t) is determined. The real-domain representation is processed to obtain a triangular matrix. In addition, at least one of the following is performed: (i) hard decision detection of a transmitted sequence and demapping of corresponding bits based on a reduced complexity search of a number of transmit sequences, and (ii) generation of bit soft-output values based on the reduced complexity search of the number of transmit sequences. The reduced complexity search is based on the triangular matrix.

  • Patent number: 8350622
    Abstract: A circuit includes a differential amplifier having a folded cascode architecture with a pair of cascode transistors. A sensing circuit senses a common mode input voltage of a differential input signal applied to the differential amplifier. A bias generator circuit generates a bias voltage for application to the pair of cascode transistors in the folded cascode architecture. The bias generator circuit is connected to an output of the sensing circuit such that the generated bias voltage has a value which is dependent on the sensed common mode input voltage. This dependence stabilizes a common mode output voltage from the differential amplifier in response to changes in the common mode input voltage.
