A Subthreshold SCL Based Pipelined Encoder for Ultra-Low Power 8-bit Folding/Interpolating ADC

Seyed Armin Tajalli, Yusuf Leblebici, Mohammad Beikahmadi

The subthreshold MOS source-coupled logic (STSCL) technique is of great interest for designing ultra low power circuits. In this paper we discuss the design of a pipelined encoder for an 8-bit folding and interpolating (F&I) analog-to-digital (ADC) data co ...

Characterization of the polarization sensitivity anisotropy of a near-field probe using phase measurements

Olivier Martin

Amplitude and phase measurements of the near-field generated by isolated subwavelength apertures in a gold film are presented. The near-field distribution of such a structure is complex and the measured signal strongly depends on the electric field compone ...

A Generalized Sampling Method for Finite-Rate-of-Innovation-Signal Reconstruction

Michaël Unser, Chandra Sekhar Seelamantula

The problem of sampling signals that are not admisible within the classical Shannon framework has received much attention in the recent past. Typically, these signals have a parametric representation with a finite number of degrees of freedom per time unit ...

A Low-Power, Low Data-Rate, Ultra-Wideband Receiver Architecture for Indoor Wireless Systems

Pierre-André Farine, Cyril Botteron, Christian Robert, Frédéric Chastellain, Uroschanit Yodprasit, Alexander Heubi, Paul Saad

Abstract—In this paper, a novel architecture for a low data-rate, low power consumption Impulse Radio (IR) Ultra- Wideband (UWB) receiver is presented in which the received UWB signal is downconverted to a given intermediate frequency (IF) rather than at b ...

Mixed-domain system representation using Volterra series

Martin Hasler

Mixed-signal systems combine analog and digital signal processing in one overall design that should be integrated as a single system on chip. At system level, the separation into isolated subsystem representations for analog and digital parts needs to be o ...

Magnetic circular dichroism in electron microscopy

Cécile Hébert

Although the analogies between the electron energy loss spectra and X-ray absorption spectra were recognized long ago, the possibility to observe the magnetic circular dichroism in the electron microscope was demonstrated only recently. This technique comb ...

On-Chip Sandwich Immunoassay in an Integrated Magneto-Optical CMOS Microsystem

Edoardo Charbon, Martinus Gijs, Ulrike Lehmann, Emile Dupont

We report on an innovative approach to on-chip detection of single fluorescently-labeled magnetic micro-particles by means of Single Photon Avalanche Diode (SPAD) arrays. Our system enables particle separation through magnetic actuation and highly sensitiv ...

The Monogenic Riesz-Laplace Wavelet Transform

Michaël Unser, Dimitri Nestor Alice Van De Ville, Katarina Balac

We introduce a family of real and complex wavelet bases of

L _{ 2 }

(\mathbb{R} ^{ 2 }

) that are directly linked to the Laplace and Riesz operators. The crucial point is that the family is closed with respect to the Riesz transform which maps a re ...

Mixed-mode implementation of particle filters

Volkan Cevher

In this paper, we develop new mixed-mode implementations for particle filters and compare them to a digital implementation. The motivation for the mixed-mode implementation is to achieve low-power implementation of particle filters. The specific applicatio ...

Hybrid continuous-discrete-time multi-bit delta-sigma A/D converters with auto-ranging algorithm

Sergio Pesenti

In wireless portable applications, a large part of the signal processing is performed in the digital domain. Digital circuits show many advantages. The power consumption and fabrication costs are low even for high levels of complexity. A well established a ...
