[Technology Report]
DSOs Tackle The Challenges Of Faster, More Complex Designs
Like an octopus, the oscilloscope on today's design bench must sprout multiple tentacles, reaching out to monitor signals in many parts of a circuit and displaying the measured values all at once—with all events synchronized to a common time...  — Stephen Grossman

[Product Innovation]
Processor Manages Heavy Lifting With Dual Gigabit Ethernet Ports
IP-based storage networks need significant horsepower to handle large tcp/ip loads. Silverback Systems' iSNAP 2100 delivers this power while offloading the host processor to support more connections. This approach also allows the host processor to...  — William Wong

[Design Application]
Protect Your High-Speed Circuits From ESD Transients
Electrostatic discharge (ESD) frequently occurs in nature, and in the electronics equipment environment, with very damaging results. Indeed, it's responsible for more than 25% of the semiconductor chip damage happening during wafer fab, through...  — Thomas G. Nagy

[Ideas For Design]
Two-Chip Digital Thermometer Delivers 0.4°C Accuracy
An LED digital thermometer with an operating range between 0°C and 150°C, 1°C resolution, and ±0.4°C accuracy is presented in the figure. This design is based on the PIC16F872...  — Ricardo Jimenez , et al.

[Ideas For Design]
Composite Amplifier Boosts Precision Of Programmable Voltage Source
Engineers often need dc voltage sources with very high precision and good resistive and/or capacitive load-driving capability for industrial applications. However, precision benchtop power supplies can be very expensive if high accuracy also is...  — Reza Moghimi

[Ideas For Design]
PLD Adds PWM Soft-Start Function To Switching Power Supplies
Switching converters sometimes use soft-start circuitry to reduce the large in-rush current that occurs when they first turn on. By employing a PLD, soft start can be added to power-supply controllers that don't natively support this function, but...  — Clive Bolton

[Editorial]
Will Impending Engineer Shortages Impede Progress?
As many companies in the electronics industry shed employees to stay competitive in these tough economic times, I wonder if we have gone past cutting the fat and now are trimming away too much of the industry's muscle. At the same time, we see a...  — Dave Bursky

[Pease Porridge]
What's All This Multiplication Stuff, Anyhow? (Part IV)
When I'm out on the road, preaching at Linear Seminars, I run into guys with good questions, every day. Some I can answer, some I can't, and others just take a long while for me to figure out a good answer. One question that I carried for at least...  — Bob Pease

[Viewpoint]
Designers Seek Silicon Architecture That Works Smarter, Not Harder
Today's most challenging system design issues place conventional IC architectures in a dubious position. Since the microprocessor was invented, Moore's Law has been the bellwether for the semiconductor industry. It states that transistor density will...  — John Watson

[Editor's Notebook]
Embedded Linux: Is It Dead Yet?
It's raining penguins. Or rather, that's what many people would like you to think. Linux vendors are laying off scores of workers. Linux publications are folding. So is it doom and gloom time for Linux lovers? Now might be a good time to...  — William Wong

[Embedded in Electronic Design]
Platform Migration
Cross-platform development is old hat for embedded engineers and programmers, but typically, there's one target platform and one development platform. Unfortunately, moving from one development platform to another often meant learning a whole new set...  — William Wong

[Embedded in Electronic Design]
Graphical Tool Aids Eclipse Developers
Dumping Eclipse into the open-source community was a smart move for IBM and a windfall for embedded developers. This open-source project (www.eclipse.org) is more than just a Java IDE. Its plug-in architecture makes it ripe for extensions like...  — William Wong

[Embedded in Electronic Design]
Two-Level Configurable Compiler Hits Multiple DSP And VLIW Targets
Efficient code generation for DSPs and VLIW processors is a difficult process. So compilers are often created for a particular processor architecture to enable programmers to employ specific features of the architecture. Altium's new Viper compiler...  — William Wong

[Embedded in Electronic Design]
LIN Development Kit Eases Low-End Network Development
Typically, a local interconnect network (LIN) is found in automotive applications, but it also suits control networks. Microchip Technology's new PICDEM LIN Development Kit makes experiments with LIN networks a bit simpler. LIN master and...  — William Wong

Dedicated Baseband Processor Breaks New Ground In 3G Designs
Greater computational complexity and the rising broadband demands of the evolving third-generation wireless standards are forcing developers to look beyond traditional digital signal processor (DSP) architectures. Since MOPS requirements for these...  — Ashok Bindra

[Forefront]
PPTCs Extend Protection To Line-Voltage Applications
Polymeric positive temperature coefficient (PPTC) devices traditionally provide resettable circuit protection against overcurrent and overtemperature conditions. Yet their low voltage ratings limit their application to secondary-side protection of...  — David G. Morrison
