  • Publication number: 20110309842
    Abstract: Methods and apparatus are disclosed to simultaneously, wirelessly test semiconductor components formed on a semiconductor wafer. The semiconductor components transmit respective outcomes of a self-contained testing operation to wireless automatic test equipment via a common communication channel. Multiple receiving antennas observe the outcomes from multiple directions in three dimensional space. The wireless automatic test equipment determines whether one or more of the semiconductor components operate as expected and, optionally, may use properties of the three dimensional space to determine a location of one or more of the semiconductor components. The wireless testing equipment may additionally determine performance of the semiconductor components by detecting infrared energy emitted, transmitted, and/or reflected by the semiconductor wafer before, during, and/or after a self-contained testing operation.

  • Publication number: 20110279327
    Abstract: A low profile Planar Inverted-F Antenna (PIFA) comprises a radiating strip, an inductive tuning portion, a vertical feed portion, and a retracted ground plane. The radiating strip is approximately parallel to the ground plane and is suspended above the ground plane by the feed element at a certain distance. Further, the radiating strip, in part or entirely, overhangs the ground plane. In this way, the radiating strip may be suspended very close to the ground plane, but yet exhibits a large bandwidth.

    Abstract: Disclosed herein are systems, apparatuses, and methods for providing a proximity coupling without Ohmic contact. Such a system includes a plurality of wireless-enabled components (WECs) that are wirelessly coupled to each other. Each WEC includes a metal-based element, a substrate, and a semiconductor layer that separates the metal-based element from the substrate. A signal is configured to be transmitted via a proximity coupling (e.g., a magnetic coupling, an electric coupling, and/or an electromagnetic coupling) between the metal-based element and the substrate without an Ohmic contact between the metal-based element and the substrate. In an example, a first subset of the plurality of the WECs is co-located on a first chip, and a second subset of the plurality of the WECs is co-located on a second chip. The first chip and the second chip may be located in a single device or in separate devices.

  • Publication number: 20110183699
    Abstract: Embodiments of the present invention are directed to a wireless resource borrowing environment enabled by a wireless bus comprising a plurality of wireless-enabled components (WECs). In an embodiment, the WECs use the wireless bus to share resource information (including resource availability information) among each others. For example, a WEC may share with other WECs information regarding its processing and memory resources. The WEC may then use the shared resource information to identify resources at other WECs that it may borrow to perform certain tasks. In an embodiment, resource borrowing is performed according to a cost-based method which optimizes resource borrowing according to a cost function. The cost function may be designed to optimize resource borrowing according to any combination of one or more factors, including power consumption, processing speed, delay, interference, error rate, reliability, load at the lender WEC, computing capability at the lender WEC, etc.

  • Publication number: 20110133835
    Abstract: Double transformer balun for maximum PA (Power Amplifier) power. A novel approach is presented herein by which conversion from a differential signal to single-ended signal may be achieved using a double transformer balun design. The secondary coils of the double transformer balun also operate as a choke for the PA supply voltage. The secondary coils can operate as an RF (Radio Frequency) trap or choke to keep any AC (Alternating Current) signal components and to pass any DC (Direct Current) components. By using a double transformer balun design, relatively thinner tracks may be employed thereby ensuring a high degree of electromagnetic coupling efficiency and high performance. Also, these relatively thinner tracks consume a relatively small amount of space on the die. The double transformer balun design also includes a matching Z (impedance) block that is operable to match the Z of an antenna or line that the PA is driving.
