Best Practices for Integrating eGaN FETs

Best Practices for Integrating eGaN FETs
Best design practices utilize the advantages offered by eGaN FETs, including printed circuit board (PCB) layout and thermal management. As GaN transistor switching charges continue to decrease, system parasitics must also be reduced to achieve maximum switching speeds and minimize parasitic ringing typical of power converters.

Lidar: A Gold Rush Is On to Help Your Car See Better

Lidar: A Gold Rush Is On to Help Your Car See Better
Developers are hard at work on the machine learning necessary for safer and more-autonomous vehicles. But all the AI in the world won’t be enough if the car relies on inadequate sensors. That was clearly demonstrated in one fatal Tesla crash that occurred in part because the car’s camera didn’t correctly identify an oncoming truck. To ensure smart vehicles have a reliable model of surrounding objects — particularly the ones the cars identify as “threats” — most rely on one or more lidars, or laser-based remote sensors.

CES 2018 in Photos: What We Remember Most

CES 2018 in Photos: What We Remember Most

LAS VEGAS — Once again the marathon that is CES is drawing to a close. Four days of trade show plus two days of media events. All sprawled across five miles of Las Vegas in some insane number of hotels and conference venues. As usual, I stuck it out so you don’t have to. Here are some of the images that struck me as interesting, weird, or just plain worth remembering:

EPC’s Wireless Power Fix: Get a Load of This Antenna

EPC’s Wireless Power Fix: Get a Load of This Antenna
Wireless power, the ability to deliver electricity to gadgets without plugging those gadgets into a cable, is a hotbed of innovation at the moment. The dominant standard, called “Qi,” is ever under attack from other efforts. This week saw interesting developments from Energous (WATT), which aims to transfer power via radio frequency transceivers, with limited results so far, and some controversy about its business. There are other contenders. On Wednesday in Las Vegas, during the Consumer Electronics Show, I met with Alex Lidow, who is founder of a privately held chip company EPC of El ... Read more

Why experts believe cheaper, better lidar is right around the corner

Why experts believe cheaper, better lidar is right around the corner
This article takes a deep dive into lidar technology. It explains how the technology works and the challenges technologists face as they try to build lidar sensors that meet the demanding requirements for commercial self-driving cars. The bottom line is that while bringing lidar costs down will take a significant amount of difficult engineering work, there don't seem to be any fundamental barriers to bringing the cost of high-quality lidar down below $1,000—and eventually below $100. That means the technology—and ultimately, self-driving vehicles that depend on lidar—should be well within ... Read more
