Improving Measurement Accuracy by Controlling Mismatch Uncertainty
7/30/2002   1 comment
Signal reflections due to impedance mismatches are a major cause of errors in RF measurement. Agilent's Anthony Lymer discusses the problem of "mismatch uncertainty" and what you can do to minimize its effect on your high-frequency system evaluations.
The Relationship of Dynamic Range to Data Word Size in Digital Audio Processing
7/16/2002   3 comments
Digital audio-processing needs vary significantly between applications. Analog Devices' John Tomarakos reviews DSP requirements for different audio systems, and discusses how audio quality is dependent on a system's dynamic range and the size of the data word used during computations.
Silicon and Chocolate: IMEC's Investment in Tomorrow's Technologies
7/12/2002   Post a comment
There really is technical life outside of Silicon Valley. TechOnLine's Jim Lipman describes the activities of IMEC, a fascinating European research center, whose activities are on the leading edge of microelectronics, nano-technology, and information and communication technology development.

There’s a further cool thing you can do with a spreadsheet that most SPICEs can’t. That’s to use the spreadsheet ‘solver’ functionality to adjust component values in the search for a better-fitting circuit – or even to find a set of component values for a circuit you can’t otherwise design.
Infineon MOSFETs have been embedded into PC boards by Schweizer Electronic AG
You now need to adjust component values to achieve some system goal, such as predefined frequency response or time behaviour, and there’s no closed method for working out those values.
As a member of the electronics design community, I am angry and disappointed with the recent deaths of 346 people due to the Boeing MAX 8 design
The theoretical advantages of GaN-based power transistors are now being realized in mainstream system designs. Power supplies for data centers and telecom switching racks are two application areas where GaN transistors show significant improvement in comparison to systems using best-in-class Silicon-based Superjunction devices.
