Compact Low-Power Cortical Recording Architecture for Compressive Multichannel Data Acquisition

Pierre Vandergheynst, Alexandre Schmid, Mahsa Shoaran, Mahdad Hosseini Kamal

This paper introduces an area- and power-efficient approach for compressive recording of cortical signals used in an implantable system prior to transmission. Recent research on compressive sensing has shown promising results for sub-Nyquist sampling of sp ...

Design of a parallel low power flash A/D converter for the sub-sampling IR-UWB receiver

Catherine Dehollain, Shenjie Wang

This paper presents the design of a dual-channel 4-bit analog-to-digital converter (ADC) for the sub-sampling impulse radio ultra-wideband receiver with the sampling rate of 2.112 GS/s. The ADC's specifications are optimized at the system level. Two parall ...

Big brother is watching you: eavesdropping to resolve family conflicts

Christof Faller

Adult animals can eavesdrop on behavioral interactions between potential opponents to assess their competitive ability and motivation to contest resources without interacting directly with them. Surprisingly, eavesdropping is not yet considered as an impor ...

A computer-assisted multi-electrode patch-clamp system

Henry Markram, Rodrigo de Campos Perin

The patch-clamp technique is today the most well-established method for recording electrical activity from individual neurons or their subcellular compartments. Nevertheless, achieving stable recordings, even from individual cells, remains a time-consuming ...

3D near-infrared imaging based on a single-photon avalanche diode array sensor

Edoardo Charbon, Juan Mata Pavia

Near-infrared light can be used to determine the optical properties (absorption and scattering) of human tissue. Optical tomography uses this principle to image the internal structure of parts of the body by measuring the light that is scattered in the tis ...

Low-Power Circuits and Systems Design for Data Acquisition and Transmission in a Wireless Cortical Implant

Vahid Majidzadeh Bafar

Minimally invasive monitoring of the electrical activity of specific cortical areas using implantable microsystems offers the promise of diagnosing neurological diseases, as well as detecting and identifying neural activity patterns which are specific to a ...

3D Near-Infrared Imaging Based on a Single-Photon Avalanche Diode Array Sensor

Matthias Wolf, Edoardo Charbon, Juan Mata Pavia

An imager for optical tomography was designed based on a detector with 128x128 single-photon pixels that included a bank of 32 time-to-digital converters. Due to the high spatial resolution and the possibility of performing time resolved measurements, a ne ...

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

Yusuf Leblebici, Alexandre Schmid, 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 ...
