What is "ground"?

Paul Rako points to a nice paper by AWR on grounding in circuit and EM simulators.

Engineering at NASA

Not everything is glamorous in engineering for space travel, or the unlimited usefulness of duct tape.

CMOS PAs

Interesting point/counterpoint on CMOS for RF power amplifiers at EETimes:
  • CMOS is the wrong technology for 3G handset PAs: "To the 3G handset user, the objectives are straightforward: I want speed and reliability. I want fast data rates and a robust connection. I want my device to work wherever I go, no matter how far from the cell tower or which part of the device I am holding. And I want great talk time. All of these 3G needs are enabled by gallium arsenide (GaAs) power amplifiers."
  • CMOS is the right technology for 3G handset PAs: "History has shown that once CMOS can meet the difficult analog performance requirements presented by an application, it always wins."

196 Mpixels camera, 380Mpixels to go...

Dalsa presents a 196 Mpixels image sensor. Getting closer to the 576 Mpixels of the human eye...

IEEEXplore watch: new IEEEXplore since yesterday

IEEE has changed its Xplore web presence.

Related, at LinkedIn's IEEE official group, an interesting discussion started by Roger Pollard:
How should IEEE Societies and Councils respond to the likely mass movement to Open Access publishing?

1. The US Government seems to be moving towards mandating Open Access for all publications arising from federally-funded research (see http://www.whitehouse.gov/open ). There are similar pressures in Europe and many other countries.

2. Approximately 70% of IEEE-Xplore usage is for articles more than two years old.

3. The above facts point to potential adverse revenue consequences to Societies and Councils of delayed Open Access. How should IEEE Societies and Councils respond? How are they already responding? What input would you like IEEE S/Cs stakeholders and decision makers to consider? How should the IEEE Technical Activities Board respond?

Wireless power overview

An overview of the status at New Scientist.
Poor transmission efficiencies and safety concerns have plagued attempts at wireless power transfer, but a handful of start-ups - and some big names, like Sony and Intel - are having another go at making it work. The last few years have seen promising demonstrations of cellphones, laptops and TVs being powered wirelessly. Are we on our way to waving goodbye to wires once and for all?

The economic realities of 450 mm

Nice article from Solid State Technology.
There continues to be a pervasive misconception that a wafer-size transition alone can provide a significant cost saving for the industry. Expectations of 30% cost savings have been repeated so often that it may seem that it is a fundamental law of wafer-size transitions. As was pointed out in SEMI's Equipment Productivity Work Group's (EPWG) paper on the Economics of 450mm, this expectation has not been based on objective analysis. The following data, based on analysis from our member companies, raise large questions which have been overlooked by IC Knowledge in their assessment.

A biologically inspired silicon vocal tract

Nice article at SPIE about an IC vocal tract: "The first integrated-circuit vocal tract, combined with a bionic ear processor in a feedback speech-locked loop, provides a new way to process speech."

ISSCC reports - III

From EETimes:
From Semiconductor International: "AMD, Intel Vie on Power Savings Ideas", related to the items yesterday on their new microprocessor architectures.
