Andrew Lacey is to fill the newly-created COO position at Integrated Graphene, a company built around a carbon-based electro-active material it brands ‘Gii’. “Andrew will be responsible for developing Integrated Graphene’s global manufacturing capabilities, enabling commercial quantity international selling of Gii into North America, Europe, the Middle East and Asia-Pacific regions,” according to the company. A chartered engineer by ...

Last week Belgian fabless chip company Melexis announced a unique inductive sensing IC that includes a tiny transformer, drive circuit and sense circuit, so Electronics Weekly decided to have a closer look. No permanent magnet, external or internal, is needed, and external magnetic fields are rejected. MLX92442 only requires a nearby electrically conductive object for triggering. It comes in either ...

Alpha and Omega Semiconductor has released a 7A 23V USB Type-C protection and reverse-blocking switch IC. Dubbed AOZ1377DI, is can be used in both Sink and Source applications and it “offers features that significantly reduce voltage drop and power loss compared to back-to-back p-channel devices”, promises the company. Instead it uses a pair of internal drain-to-drain n-channel mosfets, whose gates ...

Researchers at the Tokyo Institute of Technology have found a novel way to reduce source and drain contact resistance, and increase carrier mobility, in amorphous oxide transistors. In particular, they are amorphous indium gallium oxide (a-IGZO) thin-film transistors that are being proposed for a form of DRAM, where memory density can be increased by stacking the transistors. The problem is ...

EPC has used GaN transistors to create a high-power Class-D two-channel audio power amplifier design. Instantiated in evaluation kit EPC9192, it is capable of pushing 700W/channel into 4Ω (or 2Ω) or 350W/channel into 8Ω. Bridging the two channels results in 1.4kW drive into 4 to 8Ω. Key components, per channel, are a pair of 200V EPC2307 GaN transistors on a ...

I finally found time to try out the home-modified 1610Pro desktop cnc. And here is the result: routed from 4mm thick cast Perspex with a 1mm deep letter ‘h’, all edges machined. The routed rectangular base is 27mm tall (as I remember) and is accurate to better than 100μm. The only error was 200μm in the total length of the ...

  Concurrent Technologies has put Intel Atom x7000RE Amston Lake processors into a VME board, adding image processing and AI audio processing accelerators to the venerable form factor. CPU choice on the board, called Rhea, is either the four-core 1.5GHz x7433RE, or the two-core 2GHz x7213RE. “Whilst no longer the cutting edge of technology, VME continues to be a widely ...

Samtec has created a line of RF connectors that mount to the edge of PCB by bolting rather than soldering. They measure only 9.5mm from side-to-side where they sit on the PCB and are under 8mm from top to bottom (see photo) “These connectors are commonly used in a lab setting for high-frequency test and measurement and evaluation boards,” according ...

Congatec announced SMARC modules based on Intel’s Atom x7000RE ‘Amston Lake’ processors. “Specially designed for industrial requirements, they deliver eight processor cores, double the previous generation, while maintaining the same power consumption,” according  to Congatec. Called conga‑SA8, the modules are credit card size and operate over -40 to +85°C. Read all the latest news from Embedded World 2024 » AI ...

Supermicro has announced edge computers built around Intel’s Atom x7000RE processors. SYS-E100-14AM and SYS-E102-14AM mini-PCs have up to eight ‘Efficient’ cores had dissipate less than 12W. “While the SYS-E102 comes in a form factor of only 190 x 44 x 120 mm, these systems offer up to 16GB of DDR5-SODIMM, dual 2.5 GbE LAN ports, two independent HDMI ports, three ...
