GaN is Eyeing Silicon’s Data Center Lunch

GaN is Eyeing Silicon’s Data Center Lunch
As deep learning proliferates, the question of data center power density is once again on the rise, creating new business opportunities for specialized cloud services, hosted in facilities that can support north of 30 kW per rack, and companies in the power conversion space, who can tackle the density issue by making systems more energy efficient. Replacing silicon as the semiconductor material in power conversion chips with gallium nitrate, or GaN, leads to much smaller and more energy efficient devices that provide much faster switching.

Wireless power challenges and opportunities

Wireless power challenges and opportunities
Wireless power transfer (WPT) technology is destined, in the very near future, to rock the electrics and electrical world we live in. Eric Giler, now president of WiTricity, an MIT spinoff, gave an excellent TED presentation in 2009 entitled, "A demo of wireless electricity." In this demonstration, Giler powered a small TV via wireless power transfer—that was 2009. We have come a long way since then; please read on for a technical glimpse into this amazing field (pun intended) of opportunity for designers. EDN Network January 26, 2017 Read article Read more

Velodyne Says It's Got a "Breakthrough" in Solid State Lidar Design

Velodyne Says It's Got a "Breakthrough" in Solid State Lidar Design
Lidar is a fantastic sensor for autonomous cars. Most companies developing self-driving vehicles seem to agree that the massive amount of long range, high accuracy data that you get from lidar is necessary, especially for complicated and variable urban environments. Really, the only reason why there's been so much focus on getting autonomy to work with just cameras and radar is that cameras and radar are cheap, and lidar is ridiculously expensive.

eGaN Technology Reliability and Physics of Failure - Gate Voltage Stress Reliability

eGaN Technology Reliability and Physics of Failure - Gate Voltage Stress Reliability
The previous installment in this series focused on the physics of failure surrounding thermo-mechanical reliability of EPC eGaN wafer level chip-scale packages. A fundamental understanding of the potential failure modes under voltage bias is also important. This installment will provide an overview of the physics of failure associated with voltage bias at the gate electrode of gallium nitride (GaN) field effect transistors (FETs). Here we look at the case of taking the gate control voltage to the specified limit and beyond to investigate how eGaN FETs behave over a projected ... Read more

Faster, Smarter, Better: The Next Chip Revolution

The world around us will soon be engulfed by machines that affect our living spaces, our bodies, and our experience of light and sound, powered by a novel combination of semiconductors and miniature engines. Tasks as basic as charging a smartphone or cooking an egg—and as complex as scanning for colon cancer or powering flying drones on long journeys—stand to be transformed.

Why We'll Soon Be Living In A Class D World

Why We'll Soon Be Living In A Class D World
Class A has been the serious audiophile's gold standard for decades. Today however, we are at the early stages of a seismic shift towards widespread Class D audiophile adoption. Why? Because a new type of Class D audio is quickly approaching the performance of Class A, with benefits not enjoyed by the reigning incumbent. A new transistor technology called Gallium Nitride (GaN) is poised to uproot the high-end audio world. In fact, GaN-based Class D is much more power-efficient than traditional, MOSFET-based Class D and offers orders of magnitude better performance. Audiophile ... Read more

LiDAR, not just radar and cameras, will be critical to self-driving car safety

LiDAR, not just radar and cameras, will be critical to self-driving car safety
The chief technology officer of a technology supplier that enables Tesla's semi-autonomous Autopilot driving technology believes the carmaker is pushing the safety envelope too far. "It is not designed to cover all possible crash situations in a safe manner," Amnon Shashua, CTO and executive chairman at Israel-based Mobileye NV, told Reuters Wednesday.

How This Tech in Self-Driving Cars Is Paving a Road Beyond Silicon

How This Tech in Self-Driving Cars Is Paving a Road Beyond Silicon
In the future, self-driving cars will require laser-based sensing tech, and these systems will need new types of high-speed transistors and chips that can beat out silicon. That’s the assertion of Alex Lidow, a Stanford PhD physicist, entrepreneur, and CEO and founder of Efficient Power Conversion (commonly called EPC), a company based in El Segundo, Calif. that makes transistors and chips out of a material that operates more quickly and efficiently—and costs less than silicon.

eGaN Technology Reliability and Physics of Failure - Strain on solder joints

eGaN Technology Reliability and Physics of Failure - Strain on solder joints
The first three installments in this series covered field reliability experience and stress test qualification of EPC’s enhancement-mode gallium nitride (eGaN) field effect transistors (FETs) and integrated circuits (ICs). Excellent field reliability that was documented is the result of applying stress tests covering the intended operating conditions the devices will experience within applications. Of equal importance is understanding the underlying physics of how eGaN devices will fail when stressed beyond intended operating conditions (e.g. datasheet parameters and safe operating area). ...
