mmW local oscillator signal generator with integrathed phase shifting capabilites
The most innovative communication systems for beyond 5G and future 6G applications have to face a number of challenges related to the trade-offs between link range, power consumption and data-rate. A growing interest is put on radio frequency circuits operating at mmW and sub-THz bands because at those frequencies there are large portions of available […] >>

Management of Spectre and Meltdown information leaks in a RISC V application processor
Since 2018 and the announcement of the Spectre and Meltdow vulnerabilities, the hard-won performance gains of desktop and server processors over the past few decades have been called into question. These vulnerabilities effectively exploit the speculative and out of order execution found in all modern processors to gain in the number of instructions performed per […] >>

Development of new blue emitting organic molecule based on the hyperfluorescence
The focus today is on high luminance of the microdisplays to meet the requests for AR/VR application. The performance of current OLEDs, in terms of luminance and lifetime, especially for blue, have great difficulty in meeting these high luminance specdifications. Improvements in the efficiency and lifetime of the blue emitter are therefore mandatory. Fluorescent emissive […] >>

Coupling of advanced characterization techniques to study 2D material growth and integration
Two-dimensional (2D) materials are defined as crystalline solids consisting of a single layer of atoms, making their properties remarkable. Compared to their massive form, they can present outstanding semiconducting characteristics that can be exploited for many applications (CMOS, memories, photonics, photovoltaics, etc.). However, their integration into components via standard microelectronics processes remains a challenge and […] >>
