Webinar: Supercharging Products with Embedded RFID
June 26 @ 2 pm ET
Sponsored by SkyeTek


They may still look the same on the outside, but embedded RFID readers and software can transform products from the inside, offering manufacturers, OEMs, and product designers new opportunities for competitive advantage through increased efficiency, accuracy and product differentiation. With an seemingly unending list of products, RFID is a key technique to adding new functionality, increasing reliability and enhancing the user experience. At this webinar and interactive Q&A session, learn the difference between RFID and existing barcode and contact technologies and how embedded RFID has new applications in disposable authentication, smart shelves and cabinets, contactless payments, tracking, inventory and stock, and customizable configurations. Also catch up on unique technical and business considerations for embedded RFID and companies that are already implanting the technology.

Maintain Power-Conversion Efficiency While Saving PCB Space
By Peter Khairolomour, Applications Engineer
Analog Devices Inc.


Designers of portable electronics such as cell phones, portable media players, and GPS devices are always pushing to squeeze every ounce of battery life out of the application. In particular, in the realm of power conversion, engineers aspire to ensure that every coulomb that leaves the battery finds its way to a point-of-load (POL) without being lost or dissipated as heat.

Tiny Image Sensor Integrates MDDI Interface

Debuting as the first 0.25-in., 3-Mpixel sensor with a mobile display digital interface (MDDI), the OV3647 employs proprietary, 1.75-micron OmniPixel3 technology. It also provides a standard parallel interface, which can act as an input for a secondary camera so it can share the MDDI interface while also functioning as an MDDI hub.

Data Rate Cable Assemblies for High Speed Systems
Samtec's high speed cable systems provide flexible solutions for a variety of high speed applications. Samtec Data Rate cable systems utilize high speed connectors, miniature ribbonized coax and twinax cables, and transitional PCBs to achieve high performance cable assemblies.
High speed cable assemblies should be considered when the application requires low crosstalk, low EMI emission and susceptibility, higher frequency and less loss, or lower voltage drop.
Samtec's Data Rate Cable Group ([email protected]) is available to field questions and make recommendations on assembly design and performance.

Correct-By-Construction Layout Generation And Modification
By Arya Raychaudhuri, Senior Staff Design Engineer
Fastrack Design


Physical design verification software typically identifies faults in physical layouts by finding design-rule-check (DRC) violations and layout-versus-schematic (LVS) mismatches after layout is complete. So-called "correct-by-construction" layout generation is a method for generating and modifying polygonal features during the layout construction process so that the layout satisfies both design-rule constraints and connectivity requirements.

BEAR: Berkeley Aerobot Team

The Berkeley Aerobot (BEAR) project is a collective, interdisciplinary research effort at UC Berkeley that encompasses the disciplines of hybrid systems theory, navigation, control, computer vision, communication, and multi-agent coordination. These researchers currently operate six fully instrumented helicopters, in addition to many fixed-wing and rotary-wing vehicles under development, equipped with GPS/INS, camera, and other sensors on board, which they have been using to validate their control systems design algorithms for UAVs. In addition, they conduct pursuit-evasion games between the four ground-based robots and UAVs.

Receiver Chip Brings Broadcast TV To Laptops

Some high-end desktop PCs offer optional TV tuners, but they haven’t been practical for laptops until now. Laptops and other portable devices equipped with the FlexiTV chip set from Mirics Semiconductor can receive over-the-air TV broadcasts. And with the set’s very low bill of materials (BOM) cost, you can expect more TV receivers in laptops, portable media players, and even cell phones.

Programmable Wireless Baseband Chip Handles Any OFDM Standard

Virtually all modern wireless standards have adopted orthogonal frequency division multiplexing (OFDM) as their modulation and access method. Wi-Fi 802.11a/g/n uses it. So do the mobile and fixed versions of WiMAX 802.16 and the Korean WiBro standard. The fourth-generation cell-phone standard known as Long Term Evolution (LTE) relies on OFDM. The XG-PHS cell-phone standard in Japan and China take advantage of it as well.
