Cover Story
- Hot-swapping power
Hot-swap power controllers can make the difference between a product that lasts long enough to be a classic and one that's just a bus crash waiting to happen. - FROM EDN EUROPE: Auto industry drives embedded boundary-scan
debugging
Boundary-scan techniques continue to evolve to tackle the development and debugging of deeply embedded systems. The automotive industry's special requirements are encouraging major semiconductor and test-tool vendors to work together for a new global debugging standard.
Design Features
- Hardware and software spirit esoteric technology into everyday
things
Hard-real-time control, once the exclusive province of ivory-tower PhDs, is rapidly pervading such mundane items as cars, audio systems, and washing machines. Thanks to smart tools and system components, many engineers without PhDs can contribute to the design of these products. - Using thermistors in temperature-tracking power supplies
Simple linearizing schemes make it easy to use thermistors to implement voltage-regulator designs with temperature-dependent outputs.
Leading Edge
- High-current, surface-mount inductor includes magnetic shielding
- PC Expo has lots of "biggests" and firsts
- Tool lets designers visualize and collaborate
- Architecture targets multiprocessor SOCs
- Find rapport with Bluetooth integration
- Options expand for perceptual-digital-audio compression
- Achieve DWDM at 10 Gbps
- Analog-synthesis tool eases sizing woes
- VCSEL modules have increased power-budget link
- Tool provides interactive access
- FROM EDN EUROPE: Control fluorescent lighting for smart-building applications
- FROM EDN EUROPE: DC/DC modules build packaged power supplies
- FROM EDN EUROPE: Sense wide g ranges with micromachined sensor
- FROM EDN EUROPE: Process cuts cost for wireless silicon
- FROM EDN EUROPE: Build a measurement system with a single chip
- FROM EDN EUROPE: One dc/dc converter fits all
- FROM EDN EUROPE: VxWorks to support reconfigurable systems
How It Works
- Does electronic ink mean the end of paper?
Paper is a human-readable storage-and-display technology that requires no power source to operate. Can electronic devices ever compete with that?
Tech Trends
- LEDs move from indication to illumination
The versatile LED is now bright and colorful enough to use in applications beyond simple indicators and readouts, but you still need to grapple with issues of source drive, brightness, derating, spectral output, and viewing angle.
