Nonlinear Modeling of CMOS Compatible SiN/AlN/GaN MIS-HEMT on 200mm Si Operating at mm-Wave Frequencies

Y. Fouzi, E. Morvan, Y. Gobil, F. Morisot, Etienne Okada, S. Bollaert, N. Defrance

The performance of a CMOS-compatible SiN/AlN/GaN MIS-HEMT on 200mm Silicon substrate with high power capabilities in Ka band is evaluated. The devices show an F t /F max of 80/170 GHz for 2x50x0.15 µm 2 topology, along with outstanding and competitive large signal performance compared to GaN/SiC at…

Selective dynamic band gap tuning in metamaterials using graded photoresponsive resonator arrays

V.F. Dal Poggetto, D. Urban, F. Nistri, P.H. Beoletto, E. Descrovi, M. Miniaci, N. Pugno, F. Bosia, A. Gliozzi

The introduction of metamaterials has provided new possibilities to manipulate the propagation of waves in different fields of physics, ranging from electromagnetism to acoustics. However, despite the variety of configurations proposed so far, most solutions lack dynamic tunability, i.e. their…

Characterization of Schottky Diodes at Wafer Level for Frequency Multipliers Applications Based on RF Coplanar Measurements

Hugo Bouillaud, Yannick Roelens, Etienne Okada, Jeanne Treuttel, Priyanka Mondal, Pierre Gellie, Mohammed Zaknoune, Guillaume Ducournau

While Schottky diode for THz generation have been extensively studied over last decades, technological developments are still required to reach the physical limits of these devices, such as breakdown voltage or sub-μm devices, but also efficient thermal management in particular before their…

A Convolution-Assisted Vision Transformer for the Classification of Pancreatic Ductal Adenocarcinoma

Michael Selasi Dzamesi, Feryal Windal, Karim Hammoudi, Emmanuelle Leteurte, Halim Benhabiles

Many works that require the classification of whole slide images (WSIs) primarily involve classifying patches extracted from the WSIs. The classes from the patches are extrapolated as the class of the WSI. Pathologists, however, consider the surrounding region of a patch before classifying it. We…
