Silicon carbide ready for prime time Product News 2/25/2008 2 comments NASA thinks silicon carbide is ready to replace silicon in circuitry that must withstand ultrahot temperatures--as high as 1,000 degrees F--or deliver ultrahigh power.
Researchers measure force to move a single atom News & Analysis 2/22/2008 Post a comment Researchers at the University of Regensburg in Germany and IBM's Almaden Research Labs in California have calculated for the first time exactly how much effort is needed to drag a single atom of cobalt across the surface of different metals.
Analog's answer to FPGA opens field to masses News & Analysis 2/21/2008 8 comments By making analog circuits easier to design and simulate, researchers at the Georgia Institute of Technology hope to further the cause of analog while enabling engineers to incorporate lower-power circuitry into their products. In the same way that field- programmable gate arrays have spawned advances in digital signal processing, the Georgia Tech researchers believe their large-scale field-programmable analog array (FPAA) has the potential to seed growth in analog.
Lego Mindstorm gymnastic robot is flipping great News & Analysis 2/20/2008 Post a comment Students in Taipei used Lego MindStorm NXT to build a two-link gymnastic robot which can perform giant loops on a horizontal bar. The hand-and-bar link is a free-running passive joint. Two NXT motors are used to drive the robot-shoulder link. The students were seeking the factors to make repeatable and predictable loops although there is a suspicion of non-linear chaotic behavior in the two-motor system.
Accelerating MATLAB using MEX-files Design How-To 2/19/2008 Post a comment This article gives a quick overview of the different techniques available for speeding up MATLAB code. It covers the basics of performance profiling, vectorization, and turning MATLAB code into compiled MEX-files.

Under the Hood: When is a chip not a chip? Teardown 2/14/2008 1 comment There are many reasons why a semiconductor component might be branded with markings that differ from those of its actual manufacturer. A case in point is the Apple iPhone, which includes multiple devices from large companies (such as Broadcom, Philips, Samsung and Texas Instruments); all the devices carry Apple package markings.
Xilinx Virtex-5 User-Guide Lite Design How-To 2/13/2008 5 comments As opposed to wading through more than 1,000 pages of Virtex-5 User-Guide documentation, this "User Guide Lite " boils all the key details down into a few easily-digestible pages.
Pickled onions that bite back Programmable Logic DesignLine Blog 2/12/2008 Post a comment I recently received an email from someone who had tried one of my recipes with some success, so I thought I'd share this little scamp...
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
