[Technology Report]
The Shifting Sands Of DSM Characterization
At one time, IC design was, if not easy, then at least somewhat simpler. But as the world's semiconductor foundries plunge deeper into the submicron realm, designers face exploding complexity. Issues such as signal integrity and timing... — David Maliniak

[Product Innovation]
10-Gbit/s Ethernet Switch Chip Set Serves Up Advanced QoS At Wire Speed
Switching systems continue to be called on to deliver higher packet throughputs and higher quality-of-service levels. Switching circuits controlling the data flow must perform more and more packet analysis and routing functions at wire speeds.... — Dave Bursky

[Design Application]
Automated Testing Speeds Effective Deployment Of Java Functionality
To fulfill its "write-once, run-anywhere" promise, Java technology must be widely deployed in resource-constrained information appliances and embedded devices. In addition to limited memory resources, developers face challenges in testing this... — Contributing Author

[Ideas For Design]
Resettable High-Speed Fuse Uses FET As A Sense Resistor
This design idea describes a resettable high-speed fuse that uses only a few off-the-shelf parts, resets itself after blowing, and doesn't require a special current-sense resistor. While the circuit has been designed to switch on a negative current... — Contributing Author

[Ideas For Design]
Spread-Spectrum DC-DC Converter Combats EMI
Electromagnetic radiation (called electromagnetic interference or EMI when unwanted) is emitted by almost all electronic systems, including switching regulators. The conventional approach to suppressing EMI is to block the radiation at its source... — Contributing Author

[Ideas For Design]
Low-Cost Programmable Key Lock Uses A PC-Hardware Monitor IC
Simplicity is the key to a good security system design. The following is a simple yet powerful security system employing an ADM-1024 PC-hardware monitor as the key's decoder. The ADM1024 was designed to monitor the local temperature, the... — Contributing Author

[Editorial]
Countering Terrorism: The Ultimate Challenge To Technology
We've done it. Last month, regardless of the probable consequences, the United States and its allies responded to the September 11 terrorist attacks in the United States. For better or worse, the initial response has provoked the expected rhetoric... — Dave Bursky

[Pease Porridge]
What's All This Algebraic Equation Stuff, Anyhow? (Part 3)
As we were saying, it can be tricky to figure out a filter, yet not impossible. Let's take the example of a basic Sallen-Key filter—the low-pass one in the figure. Do we have to worry about R3 and C3? No,... — Bob Pease

[Viewpoint]
SMGPs Hold The Key To Interactive Services
We're at the dawn of a pervasive convergence of personal interactive broadband communications across a cornucopia of platforms and delivery means. This exciting convergence creates true interactive communications for users and seamless access to a... — Contributing Author

[Embedded in Electronic Design]
What You See Is Not What You Get
WYSIWIG helped define visual, "What You See Is What You Get" word processors. It also applies to debuggers. We see individual threads execute with debuggers. But what we see is not what we get: the programs may not work. Yes, we have the threads... — William Wong

[40 Years Ago]
Switching, Frequency Barriers Fall
Solid-state devices for faster switching or higher frequency operation were prominent among developments unveiled at the Electron Devices Meeting in Washington, Oct. 26-28. New advances in microwave, data-handling, and energy-source devices also... — Steve Scrupski

[40 Years Ago]
Photoconductive Cells For Industrial Use
About 1000 times more light-sensitive than photovoltaic cells, these photoconductive cells are designed for light-dependent control applications. They are available in four basic sizes: a "Compactron" type, a 9-pin type in a conventional tube... — Steve Scrupski

IC Packaging Process Raises Efficiency And Integrates Test
A packaging process developed by Amkor Technology of Chandler, Ariz., is being described by the company as the packaging equivalent of a semiconductor move from 200- to 300-mm wafers. The company's matrix-assembly-and-test process not only increases... — David G. Morrison

Self-Adaptive Silicon Implements Precision Analog In Digital CMOS
Fabless semiconductor startup Impinj Inc. has developed an innovative technology for bridging the gap between precision analog and faster digital circuits. Implementing its patent-protected self-adaptive silicon technology, the Seattle company hopes... — Ashok Bindra

[Forefront]
Support Network Forms For OpenVera SoC Verification IP
The challenges of SoC verification are manifold. Large among them is the difficulty in rounding up the verification IP needed to build complete verification suites. To address this, Synopsys Inc., Mountain View, Calif., has launched the OpenVera... — David Maliniak

Modem Tuner Integrates All Critical RF Elements
Able to dramatically simplify the front-end design of cable tuners, the Hi-IQ tuner chip (DPS7000) from LSI Logic integrates all critical RF elements onto a single chip. By eliminating all the components that require adjustments after shipping, the... — Dave Bursky
