Wireless Charging Metrics Debated

Wireless Charging Metrics Debated

Wireless charging may have a standards battle to contend with, but there’s also a major a measurement problem. The quest for convenient living and energy conservation poses a ‘Ying/Yang’ dilemma living in the age of electronics. This is certainly the case with wireless power transfer technology. This rapidly emerging technology has the promise of “cutting the cord” and displacing the need for AC/DC wall adapters and perhaps eventually wall sockets. The question now is; will wireless power increase our carbon footprint by being less efficient than the traditional plug-in AC/DC wall adapters?” Are some wireless systems more efficient than others? These are two fundamental questions that need to be examined in an energy conscious world governed by energy efficient standards.

Scientists are developing an x-ray pill you can swallow

A new product being developed might make checking for colon cancer as easy as swallowing a pill. The technology is based on a new type of chip from EPC that uses gallium nitride instead of the traditional silicon. CEO Alex Lidow told Quartz that his company’s chips can withstand the high voltage needed by the sensors inside the Check Cap.

5G base station architecture: The potential semiconductor solutions

5G base station architecture: The potential semiconductor solutions

eGaN technology is expected to be one of the most important solutions to power efficiency in base station infrastructure for 5G; the peak-to-average ratios will be worse in 5G. Envelope tracking is obvious right now as one way eGaN power transistors will do this, but over the next 3 to 5 years more applications will emerge as eGaN technology progresses.

The Mobility Imperative: Untethered Consumers!

The Mobility Imperative: Untethered Consumers!

Consumers want to be able to go wirelessly where they want, when they want. They want televisions to be seamlessly synchronized with tablets, phones, laptops, and automobiles. They want all their communication, information, and entertainment to be available immediately, with high resolution, all the time. Recently the automobile industry has caught on to this trend and has begun to show its vision of the future for the fully mobile lifestyle.

Consumers also do not want to worry about running out of battery life – no more looking for an open outlet at the airport. This untethered life is the Mobility Imperative and it is driving innovation in consumer products, which in turn, is pushing the limits of silicon-based semiconductor technology.

Why Consolidation In The Chip Industry Matters To You

Why Consolidation In The Chip Industry Matters To You

If expanding industries typically indicate vibrancy, a race to acquire and consolidate is generally reflective of the opposite – a period of slowed growth in mature, often once high-flying categories. And while many industries experience a period of stardom, followed by a sharp and steady decline, we should be extremely worried when they occur in industries that are fundamentally central to our socio-economic vitality.

Energy-Saving Material Gets a Boost

Energy-Saving Material Gets a Boost

The effort to take advantage of gallium nitride is partly a response to technical and economic factors that have slowed improvement in silicon-based chips.  While companies are still finding ways to fabricate smaller transistors in silicon, reductions in cost and power consumption have been more difficult to achieve. But gallium-nitride circuits can switch on and off much more quickly than silicon and handle higher voltages, said Alex Lidow, EPC’s chief executive. That makes the material particularly good for chores that involve power conversion.
