Highly Dynamic Spatiotemporal Organization of Low-Frequency Activities During Behavioral States in the Mouse Cerebral Cortex

Sylvain Crochet, Pierre François Philippe Le Merre

Although low-frequency (LF < 10 Hz) activities have been considered as a hallmark of nonrapid eye movement (NREM) sleep, several studies have recently reported LF activities in the membrane potential of cortical neurons from different areas in awake mice. ...

A 51.4 Mb/s FSK Transmitter Employing a Phase Domain Digital Synthesizer with 1.5 mu s Start-up for Energy Efficient Duty Cycling

Christian Enz, David Ruffieux, Nicola Scolari, Raghavasimhan Thirunarayanan

This paper presents a low start-up latency Transmitter (TX) that can achieve FSK data rates of upto 51.4 Mb/s for deployment in duty cycled microsensor nodes. Utilizing a Phase Domain Digital Synthesizer with an FBAR frequency reference, this TX has a star ...

Combined Optical and Electrical Spectrum Shaping for High-Baud-Rate Nyquist-WDM Transceivers

Camille Sophie Brès

We discuss the benefits and limitations of optical time-division multiplexing (OTDM) techniques based on the optical generation of a periodic train of sinc pulses for wavelength-division multiplexing (WDM) transmission at high baud rates. It is shown how t ...

A low-power 2.4 GHz CMOS receiver using BAW resonators

Jérémie Chabloz

It has already been a few years since the first appearance of micro-electromechanical systems (MEMS) in academic research. Since then, a broad number of devices have been designed under this generic term. Bulk-acoustic wave (BAW) resonators are among the f ...

High Frequency Bands and Estimated Local Field Potentials to Improve Single-Trial Classification of Electroencephalographic Signals

José del Rocio Millán Ruiz, Anna Buttfield, Pierre Ferrez

Non-invasive brain-computer interfaces are traditionally based on mu rhythms, beta rhythms, slow cortical potentials or P300 event-related potentials. However, there is mounting evidence that neural oscillations up to 200 Hz play important roles in process ...

An Ultralow-Power UHF Transceiver Integrated in a Standard Digital CMOS Process: Transmitter

Christian Enz

In the first part of the paper, also in this issue of the JOURNAL, the design of the frequency synthesizer and receiver section of an FSK transceiver was described. It operates in the 434-MHz ISM (Industrial, Scientific, Medical) band and is realized in a ...
