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.

Revenge Fuels Energy Fight

Revenge Fuels Energy Fight

Power conversion involves creating tiny devices that convert electricity from one form to another, enabling all manner of electrical gadgets to function. Till now, silicon had been the preferred medium for power conversion processors, but as that element reaches the limits of its efficiency, attention has focused on new materials.

eGaN FETs Yield High Broad Load Range Wireless Energy Transfer Efficiency

eGaN FETs Yield High Broad Load Range Wireless Energy Transfer Efficiency

eGaN® FETs have previously demonstrated higher efficiency in loosely coupled wireless power transfer solutions when operating on-resonance using either ZVS Class D or Class E amplifiers. Practical Wireless Power systems however need to address the convenience factor of such systems, which results in reflected coil impedances that can significantly deviate from resonance as load and coupling vary. These systems still need to deliver power to the load and hence the amplifier needs to drive the coils over a wide impedance range. Standards such as the A4WP class 3 have defined a broad coil impedance range that address the convenience factor and can be used as a starting point to compare the performance of the amplifiers. In this installment both the ZVS Class D and Class E amplifiers will be tested at 6.78 MHz to the A4WP class 3 standard with a reduced impedance range to determine the inherent operating range limits. Factors such as device temperature and voltage limits will determine the bounds of the load impedance range each amplifier is capable of driving.

GaN Trends and Applications

GaN Trends and Applications

Consumers all want new electronic gadgets to be innovative, smaller, lighter, speedy and saving more energy. To fulfill these wants, GaN technology has brought about a new era of innovations in equipping engineers with the latest generation of gallium nitride (GaN) devices that are faster, smaller, more energy-efficient, and at lower prices.

GaN gives a new life to existing solutions by reviving Moore’s Law, replacing existing silicon devices while creating unexpected industry opportunities for new applications in our daily lives. These new applications include 5G wireless communications, wireless power, virtual reality glasses, autonomous vehicles and advanced medical technology like the wireless heart pumps.

As Moore’s Law turns 50, is there any way to save it from dying? Is it worth saving?

As Moore’s Law turns 50, is there any way to save it from dying? Is it worth saving?

Alex Lidow, the CEO of Efficient Power Conversion has made it his life’s work to prolong the lifespan of Moore’s Law. How? As Intel and others have found, traditional chip technology which relies on silicon is approaching a ceiling — pretty soon, somebody is going to make a silicon chip that is as cheap and powerful as that material allows. Lidow says he’s found a semiconducting material that is superior to silicon in many ways: gallium nitride (GaN). Both in laboratories and in practice, GaN chips have outperformed silicon in a number of use cases and are also cheaper to manufacture, building on the infrastructure required to make silicon chips while being more resilient and requiring fewer protective elements.

Moore's Law at 50: The past and future

Moore's Law at 50: The past and future

“Moore’s Law is morphing into something that is about new materials,” said Alex Lidow, a semiconductor industry veteran and CEO of Efficient Power Conversion (EPC). EPC is making a possible silicon replacement, gallium nitride (GAN), which is a better conductor of electrons, giving it performance and power-efficiency advantages over silicon, Lidow said. GAN is already being used for power conversion and wireless communications, and could make its way to digital chips someday. “For the first time in 60 years there are valid candidates where it’s about superior material rather than smaller feature size,” Lidow said.

Adios, silicon: Why exotic designs are the future for the chips in your gadgets

Adios, silicon: Why exotic designs are the future for the chips in your gadgets

Chip advances have powered one technology revolution after another: PCs, the Internet, smartphones, smartwatches and, soon, self-driving cars. One company betting its future on III-V materials is Efficient Power Conversion, a 34-person startup led by Chief Executive Alex Lidow. EPC already is seeing steady revenue growth from devices that incorporate a III-V layer made of gallium nitride (GaN). In 2016 or 2017 he expects to adapt the gallium nitride manufacturing process to work for the logic circuits that do the thinking in computer processors. Because of gallium nitride's electrical properties, "you immediately get a thousand times potential in improvement" over conventional silicon, he said.

Where is GaN Going?

Where is GaN Going?

Enhancement-mode gallium nitride (GaN) transistors have been commercially available for over five years. Commercially available GaN FETs are designed to be both higher performance and lower cost than state-of-the-art silicon-based power MOSFETs. This achievement marks the first time in 60 years that any technology rivals silicon both in terms of performance and cost, and signals the ultimate displacement of the venerable, but aging power MOSFET.

The Semiconductor Revolutionary

Ashlee Vance at Bloomberg Business profiles EPC. Silicon has enjoyed some serious staying power. For going on 60 years, it’s been the semiconductor of choice at the heart of transistors—the tiny switches that power the Information Age. A valley has been named after it. Many billion-dollar empires have been forged from it. And now—look away, silicon—it may finally be on the verge of being replaced.
