Enabling Low-Power Signature Recognition for the IoT with SLIF neurons

Guillaume Marthe, Claire Goursaud, Laurent Clavier

Energy constraints are still a significant challenge in numerous IoT applications, particularly due to the excessive power consumption of microcontrollers. To overcome this limitation, novel circuit designs have been introduced, with the integration of spiking neurons and analog computing emerging…

500 GHz operational bandwidth MUTC-photodiodes with milliwatt terahertz output power levels

Ezgi Abacıoğlu, Marcel Grzeslo, Tom Neerfeld, Abdu Subahan Mohammed, J L F Estévez, Guillaume Ducournau, Andreas Stöhr

We present waveguide-integrated 1.55 μm InP-based modified uni-travelling-carrier photodiodes (MUTC-PDs) featuring coplanar waveguide outputs. The fabricated photodiodes yield an operational bandwidth of 500 GHz and milliwatt output power levels in the lower THz domain.

Autonomous radar interference detection and mitigation using neural network and signal decomposition

Dayat Kurniawan, Budiman Putra Asmaur Rohman, Ratna Indrawijaya, Chaeriah Bin Ali Wael, Suyoto Suyoto, Purwoko Adhi, Iman Firmansyah

Autonomous radar interference is a challenging problem in autonomous vehicle systems. Interference signals can decrease the signal-to-interference-noise ratio (SINR), and this condition decreases the performance detection of autonomous radar. This paper exploits a neural network and signal…

Interdigitated-comb piezoelectric phononic crystals for innovative SAW devices

R. Alcorta Galván, C. Croënne, B. Dubus, E. Eustache, A. Ngabonziza, A.-C. Hladky-Hennion

In this paper, piezoelectric phononic crystals made up of interdigitated combs in floating potential condition are studied. Calculation of the dispersion curves shows that, in addition to Bragg bandgaps due to the presence of periodic electrodes, supplementary bandgaps are present corresponding to…

Investigation of the motif activity of transcription regulators in pancreatic β-like cell subpopulations differentiated from human induced pluripotent stem cells

Eric Leclerc, Mikhail Pachkov, Lisa Morisseau, Fumiya Tokito, Cecile Legallais, Rachid Jellali, Masaki Nishikawa, Amar Abderrahmani, Yasuyuki Sakai

Pancreatic β-cells are composed of different subtypes that play a key role in the control of insulin secretion and thereby control glucose homeostasis. In vitro differentiation of human induced pluripotent stem cells (hiPSCs) into 3D spheroids leads to the generation of β-cell subtypes and thus to…

Thermoelectric characterization of crystalline nano-patterned silicon membranes

Hafsa Ikzibane, Akash Patil, Jon Canosa Diaz, Etienne Okada, Etienne Blandre, Emmanuel Dubois, Jean-François Robillard

Research towards efficient and environmentally friendly thermoelectrics proposes silicon nanostructures as possible candidates through reduction of the phononic thermal conductivity. However, there is scarce literature about experimental measurements of the thermoelectric figure-of-merit zT on…

Deep Learning-based Successive Interference Cancellation to Improve Uplink in LoRa Networks

Angesom Ataklity Tesfay, Eric Pierre Simon, Mohammed Mallik, Virginie Deniau, Laurent Clavier

This paper presents a deep learning-based successive interference cancellation (SIC) scheme to improve the uplink in the LoRa Network. The proposed receiver can decode simultaneous transmissions from multiple users on the same frequency channel with the same spreading factor. The objective of the…
