FEATURES:
Sensors and ICs simplify current measurements
Today's drive towards energy efficiency at every level makes current
the fast-growing measurement. Designers can now choose from a bewildering
variety of hardware to best implement techniques that have minimal impact on the
host circuitry.
By David Marsh, Contributing Technical Editor
WiMax wireless broadband:
Static-option questions abound, mobile lurks
Chip vendors begin to deliver enabling products despite skepticism
about what—other than a mobile essence—differentiates WiMax from earlier
wireless-broadband schemes.

Component selection and
layout for smart-battery packs
Selecting and implementing the key components of today's smart-battery
circuits present unique challenges and trade-offs. Analyzing your entire design
ensures that it will reliably meet the application's requirements.
