Phase extraction in speckle interferometry by a circle fitting procedure in the complex plane

In speckle interferometry (SI), temporal signals are amplitude- and frequency-modulated signals and exhibit a fluctuating background. Prior to phase computation, this background intensity must be eliminated. Here our approach is to build a complex signal f ...

A 0.24-nJ/bit Super-Regenerative Pulsed UWB Receiver in 0.18-mu m CMOS

Catherine Dehollain, Michel Declercq

This paper describes a receiver system design for impulse-radio ultra-wideband (IR-UWB) that operates at two carrier frequencies-3.494 and 3.993 GHz-with a 10-Mbps data rate. To reduce the power consumption of the front-end amplifiers, a super-regenerative ...

Ferromagnetic nanodisks for magnonic crystals and waveguides

Dirk Grundler

Spin wave excitations in dipolarly coupled nanodisks from permalloy are investigated. We address, both, onedimensional (1D) chains and two-dimensional (2D) arrays consisting of nanodisks of different diameter. An out-of-plane magnetic field allows us to in ...

Quantitative Analysis for Authentication of Low-cost RFID Tags

Ioannis Paparrizos

Formal analysis techniques are widely used today in order to verify and analyze communication protocols. In this work, we launch a quantitative analysis for the low-cost Radio Frequency Identification (RFID) protocol proposed by Song and Mitchell. The anal ...

Interference between PARPs and SIRT1: a novel approach to healthy ageing?

Johan Auwerx, Carlos Canto Alvarez

Poly(ADP-ribosyl) polymerases (PARPs) have traditionally been linked to chromosome maintenance and DNA repair. Recent findings identify PARPs as key modulators of metabolism through their influence on SIRT1 activity, hinting to a possible role of PARPs as ...

Coordination of uncoupled bimanual movements by strictly timed interhemispheric connectivity

Friedhelm Christoph Hummel

Independent use of both hands is characteristic of human action in daily life. By nature, however, in-phase bimanual movements, for example clapping, are easier to accomplish than anti-phase movements, for example playing the piano. It is commonly agreed t ...

Determination of the vacuum optomechanical coupling rate using frequency noise calibration

Tobias Kippenberg, Albert Schliesser

The strength of optomechanical interactions in a cavity optomechanical system can be quantified by a vacuum coupling rate g(0) analogous to cavity quantum electrodynamics. This single figure of merit removes the ambiguity in the frequently quoted coupling ...

A 0.8V 2.4GHz 1Mb/s GFSK RF transceiver with on-chip DC-DC converter in a standard 0.18µm CMOS technology

Maher Kayal, Pierre-André Farine, Steve Tanner, Frédéric Chastellain, Martin Kucera

A low-energy 2.4GHz RF transceiver supporting 1Mb/s Gaussian Frequency-Shift Keying modulation and designed to run on a 1.5V battery is implemented in a standard 0.18μm CMOS technology. The integrated DC-DC converter can provide up to 100mA to an external ...

Single Channel Speech Separation with a Frame-based Pitch Range Estimation Method in Modulation Frequency

Computational Auditory Scene Analysis (CASA) has attracted a lot of interest in segregating speech from monaural mixtures. In this paper, we propose a new method for single channel speech separation with frame-based pitch range estimation in modulation fre ...

Resource and Performance Comparisons for Different Acquisition Methods that can be Applied to a VHDL-based GPS Receiver in Standalone and Assisted Cases

Pierre-André Farine, Cyril Botteron, Jérôme Leclère

There are mainly three well-known techniques to acquire a GNSS signal. The first, called Serial Search Acquisition, consist in correlating the Pseudo-Random Noise (PRN) codes for all the codes phases and all the frequency bins. The two others make use of t ...
