Simulation-based evaluation of susceptibility distortion correction methods in diffusion MRI for connectivity analysis

Meritxell Bach Cuadra, Alessandro Daducci, Kieran O'Brien

Connectivity analysis on diffusion MRI data of the whole- brain suffers from distortions caused by the standard echo- planar imaging acquisition strategies. These images show characteristic geometrical deformations and signal destruction that are an import ...

A 2.4-GHz low power polar transmitter for wireless body area network applications

Christian Enz, Vladimir Kopta, Franz Xaver Pengg

A 2.4-GHz low power polar transmitter architecture is proposed in this paper. A dynamic biasing circuit, controlled by a digital envelope signal, is used to linearize the input-output characteristic of the overdriven class-C power amplifier. A model of the ...

A 0.18 mu m Biosensor Front-End Based on 1/f Noise, Distortion Cancelation and Chopper Stabilization Techniques

Christian Enz, Carlotta Guiducci, Yüksel Temiz, Anna Ferretti

This paper presents a novel sensor front-end circuit that addresses the issues of 1/f noise and distortion in a unique way by using canceling techniques. The proposed front-end is a fully differential transimpedance amplifier (TIA) targeted for current mod ...

Bipolar optical pulse coding for performance enhancement in BOTDA sensors

Luc Thévenaz, Marcelo Alfonso Soto Hernandez

A pump signal based on bipolar pulse coding and single-sideband suppressed-carried (SSB-SC) modulation is proposed for Brillouin optical time-domain analysis (BOTDA) sensors. Making a sequential use of the Brillouin gain and loss spectra, the technique is ...

Optimization of a DPP-BOTDA sensor with 25 cm spatial resolution over 60 km standard single-mode fiber using Simplex codes and optical pre-amplification

Marcelo Alfonso Soto Hernandez

Sub-meter distributed optical fiber sensing based on Brillouin optical time-domain analysis with differential pulse-width pairs (DPP-BOTDA) is combined with the use of optical pre-amplification and pulse coding. In order to provide significant measurement ...

Correlation-aware packet scheduling for multi-camera streaming

Pascal Frossard, Thomas Maugey, Laura Toni

In multi-view applications, multiple cameras acquire the same scene from different perspectives, which results in correlated video streams. It becomes important to exploit this correlation at the acquisition side (i.e., in the source coding) or at the rece ...

A termination scheme using intended asymmetric spatial filter response for averaging flash A/D converter

Catherine Dehollain, Shenjie Wang

Averaging network is adopted to reduce the front-end amplifier's offset in the flash analog-to-digital converter (ADC) commonly at the cost of the boundary threshold error. Such error worsens the integral-nonlinearity and introduces distortion. An averagin ...
