Leti has developed a compact antenna (with a radius of just 5 cm at 868 MHz) that can selectively read RFID tags just a few centimeters away from each other. A demonstration of the antenna—retrofitted to a commercially-available portable RFID reader—was completed at the end of the French National Research Agency project Socrate. During the […] >>

Microresonators are offering increasingly impressive “quality factors.” In other words, the duration of the vibration induced by an initial impulse is getting longer and longer. This sounds like good news for the applications in which the components will be used—and it is! However, this improved performance is creating a challenge for researchers at Leti. With […] >>

Leti’s 12 Mb germanium-antimony-tellurium phase-change memory—which could be used in tomorrow’s embedded applications—recently produced record results for performance at high temperatures, a crucial step forward in the march toward automotive applications. And major advances in simulation are providing insights into why the memory is so reliable. Leti is also working with STMicroelectronics to improve the […] >>

Synthetic chemists could soon see a new addition to the catalysts available to them. Researchers at INAC recently showed that core-shell nanocrystals (cadmium selenide-zinc sulfide) are effective catalysts. First, they are active in water, under visible light. Even better, they can transfer several electrons at once, creating complex reactions. The researchers have successfully stabilized these […] >>

A Ph.D. candidate at Leti has developed an analog-digital converter and a signal filtering architecture that are setting new energy efficiency records. The innovation leverages 28 nm FD-SOI and a new, event-driven, signal processing mode, which means the systems are activated by the signal’s behavior—such as exceeding a given intensity threshold—rather than by a clock […] >>
