Wireless-data technology: a cut above Although most R&D for wide-area wireless data targets consumer access to the
Internet, the embedded applications for wireless data are also benefiting. Advances in air
interfaces, standards, and development environments ready wireless data for your
application. --Stephen Kempainen, Technical Editor
Design Features
Add testability now to core-based chips or pay
later Designing chips with reusable cores lets you put lots of logic on a piece of silicon
but also creates difficult chip-test problems. Knowing what design-for-test techniques and
EDA tools to implement these techniques are available helps you over your system-on-a-chip
test hurdles. --Jim Lipman, Technical Editor
Tiny connectors squeeze into hand-held wireless
devices Connectors in handheld wireless systems must juggle the demands of low cost, limited
space, and rigorous technical specs at gigahertz frequencies. --Bill Travis, Senior Technical Editor
Reap benefits while simplifying dual-battery
portable power management Power-path-controller ICs can effectively switch power among various power sources in
a minimum of board space; at the same time, they meet smart-battery standards. --Mark Gurries and Timothy J Skovmand, Linear Technology Corp
Termination techniques for high-speed buses Choosing the proper bus-termination technique--parallel, series, Thevenin, ac, or
diode-based--is critical to digital-system performance. Improper termination can lead to
ringing and stair-stepping, which in turn can cause false triggering and data errors. --Karthik Ethirajan and John Nemec, PhD, California Micro Devices
