Statistical Range Analysis in RF Systems: the "Range Fallacy" Design How-To 5/5/2008 2 comments You read every paper you could get your hands on to do with propagation and path loss at the frequency you're using, and you carefully included all the known (and measured) losses, antenna gains, power outputs and sensitivities in a detailed link budget. A few days later the marketing dept arrives at your office: "You said the range would be 5 meters but we tried it at that distance and we could make it fail." What has gone wrong?
Power management in mobile devices--A view of energy conservation--Part IV Design How-To 5/5/2008 2 comments The gaps grow larger between what mobile devices can do and the amount of energy engineers can deliver. Chapter 2 from Power Management in Mobile Devices: Hierarchical View of Energy Conservation is an in-depth look at the power consumption, energy types, process and transistor technology, and packaging issues inherent in mobile device design. Part IV discusses low power process and transistor technology.
60GHz: Achieving the ultimate wireless dream Design How-To 5/5/2008 Post a comment Using sophisticated design and fabrication techniques, research labs are getting closer to realizing 60GHz chips in silicon. When that happens, consumer price points can be met and wireless design becomes a whole new ballgame. But first, engineers must overcome five major challenges.
EDA startup tackles design for reliability Product News 5/5/2008 Post a comment Startup Micrologic Design Automation Inc. (Haifa, Israel) has released what is claims is the first nanometer range EDA tool that interactively eliminates reliability issues during the early stage of the physical design.
High-power infrared emitter offers wide viewing angle Product News 5/2/2008 Post a comment Vishay Intertechnology has expanded its optoelectronics portfolio with the introduction of its first wide-viewing-angle infrared emitter in a leaded package. The device claims the industry's lowest forward voltage of 1.45 V at 100 mA and 2.15 V at 1 A.
French group readies NFC-enabled speakers Product News 5/2/2008 Post a comment French consumer electronics manufacturer Parrott (Paris) is readying a range of speakers that will incorporate Near Field Communications tags supplied by Innovision Research and Technology plc (Cirencester, England).
Icera moves HSPA modem to 65-nm Product News 5/2/2008 Post a comment Icera Inc., a fabless semiconductor startup that has developed the Livanto wireless modem chipset supporting high-speed packet access (HSPA), has announced the customer sampling of the second-generation of the chipset.
HANA 2.0 home networking adds HD video QoS guarantee, discovery and DRM Design How-To 5/2/2008 Post a comment HANA 2.0 design guidelines incorporate new standards for device discovery, universal remote control of devices, bandwidth reservation for HD video, and zone-style DRM encompassing the entire home. At a CES demo in January, HANA showed how existing coax cables, CAT-5, and optical fiber and wireless could all be used within a HANA home entertainment network to deliver real time multi-room, multi-stream HD video.
16-bit, 105-Msps serial output A/D converter conserves FPGA I/O pins Product News 5/1/2008 Post a comment With a high speed 2-wire serial interface, the LTC2274 from Linear reduces the number of data I/O lines required between a 16-bit A/D converter and the FPGA from 16 CMOS or 32 LVDS parallel data lines to a single, self-clocking, differential pair communicating at 2.1-Gbit/s, freeing up valuable FPGA pins.
Low-cost, versatile Class D amplifiers line debuts Product News 5/1/2008 Post a comment Maxim Integrated Products has introduced the MAX9736A/B, a family of versatile single-supply, filterless Class D speaker amplifiers, which provide high-performance, thermally efficient amplifier solutions at the lowest solution cost.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
January 2016 Cartoon Caption ContestBob's punishment for missing his deadline was to be tied to his chair tantalizingly close to a disconnected cable, with one hand superglued to his desk and another to his chin, while the pages from his wall calendar were slowly torn away.122 comments
