Artisan completes Nurlogic acquisition News & Analysis 2/21/2003 Post a comment Artisan Components, Inc. (Sunnyvale, Calif.) announced the completion of its acquisition of NurLogic Design Inc. (San Diego), a provider of analog intellecutal property (IP) and high-bandwidth connectivity cores.
Integration eases buck regulator design Product News 2/20/2003 Post a comment Five Little Foot plus Driver power semiconductors from Siliconix, a Vishay Intertechnology company, have been designed to simplify the use of n-channel MOSFETs in high-frequency buck regulators.
Removing Pessimism from Crosstalk Analysis News & Analysis 2/20/2003 Post a comment As designers make the leap to 130-nm and smaller geometries, mitigating crosstalk becomes an even bigger headache. By combining techniques, like buffer-insertion, with off-the-shelf EDA tools, designers can greatly improve their crosstalk capabilities.
Practical applications of digital filters News & Analysis 2/20/2003 Post a comment In part 3, David Zaucha offers examples of two practical digital audio applications for filters. The first example is an equalization of a small monitor loudspeaker. The second example is an electronic crossover for a 3-way loudspeaker.
Understanding losses is key to state-of-the-art interfacing News & Analysis 2/19/2003 Post a comment The new signal data rates have changed the interface arena completely. The IC manufacturers and tool makers have come up with a number of methods that may save you money and extend life of old components and materials. This is the time when even experienced digital designers and system engineers need to go back to book and application notes, says one our favorite contributors, signal integrity guru Mike Grabois.
Active cooling techniques drive PC thermal management News & Analysis 2/19/2003 Post a comment Miniaturization and portability trends in combination with increasing performance are contributing to the well know problem of heat concentration and dissipation in modern electronic appliances. From the February issue of PA magazine, a Fairchild scientist explores the prospects for active cooling.
What Causes Batteries to Fail? News & Analysis 2/19/2003 Post a comment Battery design is a critical element in today's portable applications. Here's an inside look at why battery fail and some techniques for circumventing these problems.
Mobile networks hit noise hurdles News & Analysis 2/14/2003 Post a comment The emergence of wireless ad hoc networks means that multiple, diverse wireless devices will be operating in close proximity. In particular, the coexistence of IEEE 802.11b and IEEE 802.11g with Bluetooth personal-area networks will be an important user satisfaction issue.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
