GaN power transistors can shrink AC‑DC power supplies and cut losses but, to get the best out of them, their gate drive waveform needs careful attention. As a German team pointed out at ISSCC, GaN transistors have a threshold voltage of ~1V, which makes them vulnerable to spurious turn‑on through the Miller capacitance, particularly when …

Apple is talking to China’s Yangtze River Storage Technologies about sourcing NAND, reports the Nikkei. It is possible that Apple, whose products are assembled in China, is being pressured by China to buy from Yangtze River, and it is not known what quantities are being discussed. Analysts are sceptical about the ability of the emerging …

Home Secretary Amber Rudd says she does not rule out forcing companies to adopt blocking software for IS propaganda which was developed in a government-sponsored project by ASI Data Sciences. On the face of it, legislating to force sites to install the software seems a good idea. Then, of course, you look at the precedent …

Back in October I was pondering the creation of accurate micro-voltages from a microcontroller. What makes this so difficult is the voltage offset created by current in the microcontroller bond wire, amongst other things. Update – see ‘filtering’ below Anyway, I finally got around to trying it, and measuring the voltages. Pulses came from an …

Arm has announced a suite of IP, collected together under the provisional title of Project Trillium, to bring machine learning to edge devices. The suite includes scalable machine learning and object detection processors, claimed to enable trillions of machine learning operations per second on mobile devices. As well as machine learning, the suite is intended …

Over the course of 2017 packaged LEDs suffered only minor price erosion, although 2018 could prove to be a different story, while SSL lamp sales are near a peak but luminaire sales will grow through 2022.

Today, DAX announced the SDKs for Python and .NET , support for new T2 instances in all supported regions. T2 instances provide a baseline level of CPU performance and can be more cost-effective for test and development workloads or production applications that require smaller caches. DAX is now general availability in the Asia Pacific (Singapore) and Asia Pacific (Sydney) Regions. DAX is already available in the US East (N. Virginia), US West (Oregon), US West (N. California), EU (Ireland), Asia Pacific (Tokyo), Asia Pacific (Mumbai), and South America (São Paulo) Regions.

Network Load Balancer, designed to handle millions of requests per second while maintaining ultra-low latencies, is now available in the AWS EU (Paris) Region. Network Load Balancer is optimized to handle volatile traffic patterns while using a single static IP address per Availability Zone. It operates at connection level (Layer 4), routing connections to Amazon EC2 instances, containers, and IP addresses based on IP protocol data. It also preserves the client-side source IP, allowing applications to see the IP address of the client that can then be used by applications for further processing.
