Corrigan says chip industry in 'wait-and-see' mode News & Analysis 8/31/2004 Post a comment The semiconductor industry has adopted a "wait-and-see" attitude marked by vast uncertainties over the direction of oil prices, instability in Iraq and the presidential election, LSI Logic Chairman and Chief Executive Wilfred Corrigan said. Brian Fuller did this interview.
In Silicon We Trust Product News 8/30/2004 Post a comment For the most part, we all trust in the reliability of our semiconductor devices. This book addresses the soft error issues that can corrupt systems that otherwise function perfectly.
On The Cusp Product News 8/30/2004 Post a comment One thing you can bet on with a reasonable level of confidence. That is that communications will not go away. Our societies and planet are 'wired', physically, or wirelessly.
NOR Shall We Flash Product News 8/30/2004 Post a comment Are the days numbered for NOR Flash architectures? I think they will always be around, but, NAND Flash is making inroads at eliminating NOR altogether in som applications.
DSP-based fiber optic gyro comes in two configurations Product News 8/30/2004 Post a comment KVH Industries, Inc.'s new DSP-4000 series fiber optic gyro (FOG) comes in both single- and dual-axis configurations. They are specifically designed to provide the military with a high-performance, low-cost successor to mechanical gyros, according to KVH.
Op amp with unity-gain stability and low noise zips along at 1GHz News & Analysis 8/30/2004 Post a comment The Analog Devices AD8045 operational amplifier combines a voltage-feedback architecture, unity-gain stability, and a pin-out optimized for high-performance systems. Not bad, but there's more. It provides 1-GHz speed, low noise, and low distortion as well. It makes the op amp a good fit for medical instrumentation, ATE, and data-acquisition systems.
Fast POLs meet VRM10 specs News & Analysis 8/30/2004 Post a comment Artesyn Technology's new VRM10 series of point-of-load (POL) DC/DC converters, for meeting the core requirements of latest-generation processors and fast switching logic, offer up to 85 amps at 1.4 volts and a raw transient response of up to 930 amps/microsecond. The open-frame, single-board series includes the VRM10-80-12-P, with a maximum continuous current rating of 80 amps, and a load-line impedance of 1.24 milliohms (maintaining load regulation to 1.24 mV/A) for Pentium 4 processors. The VR
Ultrasound innards determine IC choices News & Analysis 8/30/2004 Post a comment There are major trade-offs to be considered when designing ultrasound front-end ICs, writes an Analog Devices engineer. Performance parameters in the ICs affect diagnostic performance and, conversely, system configuration and objectives affect the choice of components. It is essential for designers to understand these trade-offs, he says.
Wireless tech allies with low-power gear News & Analysis 8/30/2004 Post a comment Ultralow-power radio-frequency technologies are spurring the development of innovative medical tools, from "camera capsules" that can be swallowed to implanted devices that wirelessly transmit patient data. A Zarlink engineer gives details.
Chips analyze the human body News & Analysis 8/30/2004 Post a comment The application of fundamental semiconductor technologies to medicine, whether in the form of microarrays, microfluidics or neuro chips, is yielding tangible products, writes Junko Yoshida in an introductioh to an EE Times article package on medical electronics. She cites a report that says, as with automotive, semiconductor electronics are seen as the magic which saves the increasingly pressured health care industry.
More insights: Analyst still says hold News & Analysis 8/30/2004 Post a comment Doug Freedman of American Technology Research listened carefully to Semtech, a player in the market for Pentium VRM components. He saw a 53 percent revenue growth over the past year, but worries that the shrinking book-to-bill ratio is a sign for the coming quarter. He still has some favorites in the analog camp.
-48 V diode-OR controller saves power Product News 8/30/2004 Post a comment Linear Technology's LTC4354 is a -48 volt diode-OR controller chip for high availability systems. It meets the requirements of the AdvancedTCA telecom spec. With the LTC4354, users control two external N-channel MOSFETs in the redundant supply paths instead of traditional OR-ing diodes (which have a higher voltage drop) to dramatically improve efficiency and eliminate bulky heat sinks. The IC is available in a 2-by-3 mm DFN package.
The Week in Review: August 22 to 28 News & Analysis 8/27/2004 Post a comment Gathered below are the top five stories for the week beginning Sunday August 22, 2004, as ranked by Silicon Strategies' readers, up to and including Thursday August 26. The ranking is based on the number of reader "views" or "hits" on a particular article.
Will the real offset voltage please stand up Product News 8/27/2004 Post a comment Input offsets are composed of a lot more than the initial offset specified on the data sheet. There's also a drift with temperature, a drift with supply voltage, and more. How seriously should you take them? It depends on whether you are building toys or airplanes, says Bill Klein.
