Millimeter-wave to near-terahertz sensors based on reversible insulator-to-metal phase transition in Vanadium dioxide
Millimeter-wave (mm-wave) and terahertz (THz) detection has opened a significant research direction in imaging, sensing, spectroscopy, and ultrafast wireless communication.The sensitivity of the phase transition to electromagnetic waves in Vanadium dioxide ...
EPFL2022High Tuning Range Spiking 1R-1T VO2 Voltage-Controlled Oscillator for Integrated RF and Optical Sensing
Mihai Adrian Ionescu, Teodor Rosca, Fatemeh Qaderi Rahaqi
In this work we propose and experimentally validate a relaxation spiking oscillator architecture with ultra-high tuning range (higher than 400%, from 5KHz to more than 25kHz when the control voltage is varied from 2.5 to 5V) that exploits the reversible me ...
IEEE2021An Eight lanes 7Gb/s/pin Source Synchronous Single-Ended RX with Equalization and Far-End Crosstalk Cancellation for Backplane Channels
Volkan Cevher, Cosimo Aprile, Yusuf Leblebici, Alessandro Cevrero, Lukas Kull, Thomas Toifl
This paper presents a versatile crosstalk cancellation scheme for single-ended multi-lane backplane links. System-level investigations show that a scheme, which combines analog filters and decision-feedback crosstalk compensation on the receiver (RX) side ...
2018Objective Speech Intelligibility Assessment through Comparison of Phoneme Class Conditional Probability Sequences
Hervé Bourlard, Raphaël Marc Ullmann
Assessment of speech intelligibility is important for the development of speech systems, such as telephony systems and text-to-speech (TTS) systems. Existing approaches to the automatic assessment of intelligibility in telephony typically compare a referen ...
2015Forge: Generating a High Performance DSL Implementation from a Declarative Specification
Domain-specific languages provide a promising path to automatically compile high-level code to parallel, heterogeneous, and distributed hardware. However, in practice high performance DSLs still require considerable software expertise to develop and force ...

Idiap2014Statistical models of effective connectivity in neural microcircuits
To appreciate how neural circuits in the brain control behaviors, we must identify how the neurons comprising the circuit are connected. Neuronal connectivity is difficult to determine experimentally, whereas neuronal activity can often be readily measured ...
EPFL2014JavaScript as an Embedded DSL
Martin Odersky, Tiark Rompf, Nada Amin, Grzegorz Kossakowski
Developing rich web applications requires mastering different environments on the client and server sides. While there is considerable choice on the server-side, the client-side is tied to JavaScript, which poses substantial software engineering challenges ...
Springer Berlin Heidelberg2012Optimizing Quantize-Map-and-Forward Relaying for Gaussian Diamond Networks
Christina Fragouli, Ayan Sengupta, I-Hsiang Wang
We evaluate the information-theoretic achievable rates of Quantize-Map-and-Forward (QMF) relaying schemes over Gaussian N-relay diamond networks. Focusing on vector Gaussian quantization at the relays, our goal is to understand how close to the cutset uppe ...
Ieee2012Experiment-Driven Characterization of Full-Duplex Wireless Systems
We present an experiment-based characterization of passive suppression and active self-interference cancellation mechanisms in full-duplex wireless communication systems. In particular, we consider passive suppression due to antenna separation at the same ...
