February 25, 2013     Power management using a single-chip solution Bob Frostholm | Contributor From the deepest sub nanometre processors to the analogue I/O, having power management devices in the same box makes a lot of sense. However, power management is more than developing solutions that run cool and conserve power. It's also about managing cost. With today's plethora of fifteen and twenty cent chips, it's easy to assume your design is financially viable. But is it?

This article covers Big Data Analytics and VoLTE device testing. Accelerating pre-silicon validation As the complexity of designs being prototyped on FPGAs increases, the need for better debugging techniques becomes stronger. Here's a look at the advantages and constraints of some debugging techniques for FPGAs. more online...   Design Ideas Use transistors to drive LEDs to light the path Low-power LEDs, which come in finished packages, are appealing for outdoor lighting, but you must have a way to drive them. A simple two-transistor, two-resistor circuit proves to be a good fit for this application. Illuminate LED without wasting energy A typical LED driver circuit uses a transistor to provide current and a series resistor to decrease the voltage you apply to the LED. Learn how to employ an inductor to store energy and deliver current in this article. more online...     Advances in Conformal Coatings: Enhancing Reliability of Innovative Technologies Conformal coatings have been used in the electronics, automotive, defense, aerospace and medical device industries for many years in a number of surface modification roles, including: • Isolate/protect device surfaces from various environments  • Provide selective or overall electrical insulation  • Improve lubricity/reduce tackiness ...

Literally get a taste of data with Tongueduino Signals from the sensor are converted into pulses of electric current, which the tongue "reads" as a pattern of tingles. Electric grid secured by quantum cryptography A quantum cryptography research team had successfully completed a demo of securing control data for electric grids. Design success results from good design-for-assembly Engineers must also consider product characteristics beyond functions, user interfaces or operating conditions. Novel imaging film to turn objects into sensors The luminescent concentrator-based imager may give users full gesture control without cameras or motion trackers. more online...   Product Center 4G LTE-A modem touted as industry's smallest Broadcom's BCM21892 combines a full-featured cellular base band with a world-band radio in a footprint. Maxim's LTE/3G RF transceiver targets HetNet MAX2580 supports all LTE bands from Band 1 to Band 41 and includes 2x2 MIMO RF to Bits architecture. Nvidia outs mobile processor with integrated 4G LTE The Tegra 4i features 60 custom GPU cores, a fifth battery saver core and a version of the i500 LTE modem. Atmel's SSL LED drivers boast improved colour control The devices achieve the target correlated colour temperature coordinate and replicate the colour spectrum. iWatt rolls out SSL LED driver ready for wireless use The iW3630 maintains an extremely high power factor (PF) at loads down to 20 per cent of full load. more online...     News | Products | Design Features | Design Ideas | Regional Roundup | Tech Impact     EDN China | EDN Taiwan | EDN Japan | EDN | EDN Europe About EDN Asia | Contact Us
