Reduction of Fixed-Position Noise in Position-Sensitive, Single-Photon Avalanche Diodes

By ignoring events originating in noisy areas of a position-sensitive single-photon avalanche diode (SPAD), reduction of noise from fixed-position defects is experimentally shown. Additional experimental results from a position-sensitive SPAD integrated in ...

A 16-channel 220 µW neural recording IC with embedded delta compression

Alexandre Schmid, Yusuf Leblebici, Vahid Majidzadeh Bafar

A 16-channel neural action potential recording IC suitable for large-scale integration with multi-electrode arrays (MEAs) is presented. A closed-loop gain of 60 dB in the action potential band is achieved by cascading differential gain-stages utilizing a n ...

Clock jitter estimation in noise

Ali H. Sayed

Clock timing jitter refers to random perturbations in the sampling time in analog-to-digital converters (ADCs). The perturbations are caused by circuit imperfections in the sampling clock. This paper analyzes the effect of sampling clock jitter on the acqu ...

Fully-integrated CMOS Probes for Magnetic Resonance Applications

Jens Anders

Techniques based on spin resonance effects are amongst the most powerful analytical methods in both modern chemistry and medicine. Recent years have seen a trend toward scaled-down detection coils, exploiting the fact that a reduction of the detector size ...

Strategies for Delay-Limited Source-Channel Coding

Marius Kleiner

In point-to-point source-channel communication with a fidelity criterion and a transmission cost constraint, the region of achievable cost and fidelity pairs is completely characterized by Shannon's separation theorem. However, this is in general only true ...

MR Spectroscopy of the Human Brain With Enhanced Signal Intensity at Ultrashort Echo Times on a Clinical Platform at 3T and 7T

Rolf Gruetter, Giulio Gambarota

Recently, the spin-echo full-intensity acquired localized (SPECIAL) spectroscopy technique was proposed to unite the advantages of short TEs on the order of milliseconds (ms) with full sensitivity and applied to in vivo rat brain. In the present study, SPE ...

Low-power and low-voltage delta-sigma analog-to-digital converters for digital radio in standard CMOS technology

Nicola Scolari

The transceivers of a wireless sensor network (WSN) have to fulfill the low-power and low-voltage constraints. The WiseNET project has already proven that it is possible to design a receiver working at 1V and consuming less than 2mW. However this transceiv ...

Nonlinear low noise particle-in-cell simulations of electron temperature gradient driven turbulence

Laurent Villard, Trach-Minh Tran, Alberto Bottino, Sébastien Jolliet, Ben McMillan

In this Letter, it is shown that global, nonlinear, particle-in-cell (PIC) simulations of electron temperature driven turbulence recover the same level of transport as flux-tube codes when the level of statistical noise, associated with the PIC discretizat ...

Shot noise influence in reconstructed phase image SNR in digital holographic microscopy

Christian Depeursinge, Tristan Colomb, Etienne Cuche, Frédéric Montfort, Pierre Marquet, Florian Charrière

In digital holographic microscopy, shot noise is an intrinsic part of the recording process with the digital camera. We present a study based on simulations and real measurements describing the shot-noise influence in the quality of the reconstructed phase ...
