A new optimization approach for the automatic design of Sigma Delta-modulators

Jens Anders

In this paper, a new methodology for the automated design of one-bit internal quantizer Sigma Delta-modulators is presented. The core of the method is an NTF prototype generation in the DT-domain based on the quasilinear quantizer modeling, that maximizes ...

Noise and small-signal modeling of nanoscale MOSFETs

Ananda Sankar Roy

After years of intensive research effort, the design of RF integrated circuits in CMOS has now reached a wide acceptance for industrial designs. This is due to the high unity gain frequency and low-noise performance of today's deep sub micrometer MOS trans ...

Noise Modeling in Lateral Nonuniform MOSFET

Christian Enz, Jean-Michel Sallese, Ananda Sankar Roy

In this paper, we present an analytical noise modeling methodology for lateral nonuniform MOSFET. We demonstrate that the noise properties of lateral nonuniform MOSFETs are considerably different from the prediction obtained with the conventional Klaassen- ...

High-resolution MEA platform for in-vitro elecrogenic cell networks imaging

Kilian Imfeld, Luca Berdondini

Abstract—A platform based on an active-pixel-sensor electrode array (APS-MEA) for high-resolution imaging of invitro electrogenic cell cultures is presented, characterized and validated under culture conditions. The system enables full frame acquisition at ...

Ultrawide Bandwidth Signals as Shot-Noise: a Unifying Approach

Andrea Ridolfi

We present a shot noise based model for a large family of ultrawide bandwidth (UWB) signals. These include time-hopping and direct-sequence signaling with pulse position, interval, and amplitude modulations. Each specific signal is constructed by adding fe ...

Hall sensor and method of operating a Hall sensor

Giovanni Boero, Radivoje Popovic, Pavel Kejik, Predrag Drljaca

A Hall sensor comprises a Hall element (1; 30; 31; 60) and an amplifier (2; 32; 33). The Hall element is placed inside the amplifier so that the current flowing through the Hall element also flows through the transistors of an amplifier stage of the amplif ...

Ammonia trace measurements at ppb level based on near-IR photoacoustic spectroscopy

Luc Thévenaz, Jean-Philippe Besson

A photoacoustic sensor using a laser diode emitting near 1532 nm in combination with an erbium-doped fibre amplifier has been developed for ammonia trace gas analysis at atmospheric pressure. NH3 concentration measurements down to 6 ppb and a noise-equival ...

Electronic fluctuations in multi-walled carbon nanotubes

Arnaud Magrez

We report on the low-frequency electronic noise properties of individual multi-walled carbon nanotubes (CNTs). We present experimental evidence of the key role played by the structural quality of the tube and its gaseous environment on the excess noise lev ...

A dynamic supply CMOS RF power amplifier for 2.4GHz and 5.2GHz frequency bands

Maher Kayal, Cédric Meinen

An implementation of a dynamic supply RF power amplifier (PA) in 0.11 mu m CMOS technology occupying a total area of 1.35mm(2) is presented. Two-tone measurement results at 2.4 and 5.2GHz show that the system can deliver over 16dBm linear output power with ...
