A bio-inspired fast swarming algorithm for dynamic radio access

The goal of this paper is to propose a bio-inspired algorithm for decentralized dynamic access in cognitive radio systems. We study an improved social foraging swarm model that lets every node allocate its resources (power/bits) in the frequency regions wh ...

Subthreshold Current-Mode Delta-Sigma Quantizer with 3-Decade Scalable Sampling Rate and pico-Ampere Range Resolution

Seyed Armin Tajalli, Yusuf Leblebici

A current-mode

\Delta\Sigma

analog-to-digital data converter (ADC) for biomedical readout front-end systems is being presented. The core of this circuit is a current-controlled ring oscillator (CCO) whose oscillation frequency is proportional to the inpu ...

Fully differential low-noise amplifier with offset reduction for high-resolution neural signal recording

Pierre-André Farine, Steve Tanner, Urs Alexander Müller

A prototype of a high-density multielectrode array for in vitro recording of electrogenic cell networks has been developed. On a surface of 1.92x1.92mm2, it includes 32x32 pixels with a dimension of 60x60µm2. For local amplification of the sensed extracell ...

Low power frequency synthesizer for mobile communications systems

Imre Kovacs

A novel frequency synthesizer with a strong emphasis on low-power consumption (2mW) was developed for this thesis. A BAW-resonator was used for the design of the high-frequency oscillator. The BAW's high Q-Factor ensured a minimal power consumption, while ...

A Low-Noise CMOS Receiver Frontend for NMR-based Surgical Guidance

Giovanni Boero, Jens Anders

In this paper a novel architecture for an integrated NMR receiver front-end for surgical guidance applications is described. While the chip consumes only 9 mA supply current from a 3.3 V power supply it has a measured input referred noise density of 0.7 nV ...

Reducing the number of comparators in multi-bit ΔΣ modulators

Maher Kayal

Multi-bit feedback, being one way of lowering ΔΣ modulators power consumption, has a major obstacle: the number of components in the internal analog-to-digital converter (ADC) and digital-to-analog converter (DAC). Nevertheless, the number of comparators i ...

Obtaining Binaural Room Impulse Responses from B-Format Impulse Responses

Christof Faller, Fritz Menzer

Given a set of head related transfer functions (HRTFs) and a room impulse response measured with a Soundfield microphone, the proposed technique computes binaural room impulse responses (BRIRs) which are similar to binaural room impulse responses that woul ...

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 ...
