Switch-Mode ICs Promote Efficient Power
Management, Part 1: Switch-Mode Fundamentals By Sam Davis, Contributing Editor
A switch-mode converter circuit uses a controlled power
semiconductor switching technique along with an inductor, transformer,
or capacitor as an energy-storage element to transfer dc power from its
input to its output. In a basic switch-mode converter, a
dc-to-pulse-width converter IC accepts a dc input and produces square
waves applied to a power semiconductor switch.
Parts Add Up To Home Theater PC By Bill Wong, Embedded/Systems/Software Editor
Home theater PCs aren’t new. But getting one that works,
especially with HDTVs and HDMI, is now a lot easier with AMD’s Maui
AMD Live! This platform is designed for Microsoft Vista Media Center and
AMD Athlon processors.
There are hundreds of versions of Linux, including embedded-specific
distributions like TimeSys, MontaVista, and Wind River Linux, and
well-known desktop/server distributions such as Red Hat’s Enterprise
Linux and Novell’s SUSE.
The ABCs Of Fiber Bragg Gratings By Fredrik Sjostrom, Proximion Fiber Systems AB
As the demand for bandwidth and high-speed transport grows, so does
the use of fiber-optic based transport. One of the enabling technologies
associated with optical transport are Fiber Bragg gratings (FBGs). This
tutorial will introduce the concept of FBGs and describe the advantages
provided by use of FBGs for chromatic dispersion compensation.

Noise in low-level measurements can come from a number of different
sources, including motors, office machines, power demands, and the
switching supplies found in office equipment. Learn tips on what
features to look for in the power supply, and how to minimize the noise
in your test setup.

10-GHz Divide-By-100 Prescaler Connects To
100-MHz Counter By Wayne Ryder, SRI International
The prescaler described here connects to the front end of a 100-MHz
frequency counter to extend its coverage range to 10 GHz. The circuit is
a far less expensive way to measure frequencies above 100 MHz than
buying a 1- or 10-GHz frequency counter.

USB Makes A Move Inside The Box By Bill Wong, Embedded/Systems/Software Editor
USB is ubiquitous, but it’s usually used to connect boxes like PCs
and laptops to other devices. The type of USB hosts are changing
already, with USB sockets on printers and even HDTVs providing access to
USB flash drives. Playing a hi-def movie from a flash drive is no longer
a goal but a reality. But USB inside the box is a much different story.
The .NET Micro Framework is a platform that enables developers to
more quickly develop embedded systems that are smart, securely connected
and easier to manage. Jonathan Kagle, Microsoft's .NET Micro Framework
Senior Program Manager, introduces us to some of the hardware developers
are using in Micro Framework devices, including entries from SJJ
Embedded Micro Solutions, Crossbow, GHI Electronics, Atmel, and Digi
International.
BASF and OSRAM have created the first organic LED (OLED) to achieve
a light yield of more than 60 lumens/W while also meeting the
international Energy Star SSL Standard for color requirements.

Optically Isolated Sigma-Delta Modulator
Fortifies Industrial Motor Designs
Announced as one of the industry’s first optically isolated
sigma-delta modulators using an external clock to provide direct
measurement of motor phase currents in power inverters, the CMOS-based
ACPL-796J uses an external clock that allows synchronized data
conversion between the current sensor and controller.
