A closed core microfluxgate sensor with cascaded planar FeNi rings

Pavel Kejik, Ozge Zorlu

In this paper, we present a new microfabricated fluxgate sensor structure using cascaded planar rings as the ferromagnetic core. The planar ring structures provide closed magnetic excitation loops enabling uniform core saturation with relatively small exci ...

Power Distribution Paths for 3-D IC

Giovanni De Micheli, Vasileios Pavlidis

Distributing power and ground to a vertically integrated system is a complex and difficult task. Interplane communication and power delivery are achieved by through silicon vias (TSVs) in most of the manufacturing techniques for three-dimensional (3-D) cir ...

A single-chip array of NMR receivers

Giovanni Boero, Jens Anders, Paul Sangiorgio

We present the first single-chip array of integrated NMR receivers for parallel spectroscopy and imaging. The array, optimized for operation at 300 MHz, is composed of eight separate channels, with each channel consisting of a detection coil, a tuning capa ...

An adaptive model of overheating risk

Darren Robinson, Frédéric Haldi

Based on analogy between the charging and discharging of humans' tolerance to overheating stimuli and that of charge in an electrical capacitor, this paper proposes a simple mathematical model for predicting overheating risk given a set of measured / simul ...

Design of a 12-bit low-power SAR A/D Converter for a Neurochip

Pascal Andreas Meinerzhagen

Cutting-edge CMOS neurochips, which consist of a Microelectrode Array (MEA) manufactured on top of CMOS circuitry, allow the recording of the electrical activity of neural networks in-vitro, and their stimulation. As CMOS technology continues to scale down ...

An integrated adaptive model for overheating risk prediction

Darren Robinson, Frédéric Haldi

Based on the results from a field survey campaign, this article describes three new developments which have been integrated to provide a comprehensive basis for the evaluation of overheating risk in offices. Firstly, a set of logistic regression equations ...

Model to predict overheating risk based on an electrical capacitor analogy

Darren Robinson, Frédéric Haldi

It is important for building designers to be able to judge if a space is likely to overheat, whether to determine if HVAC plant is required or to design this out by passive means. To this end several overheating risk criteria have recently been published. ...

Common-mode Oscillation in Capacitive Coupled Differential Colpitts Oscillators

Christian Enz, Uroschanit Yodprasit

A simple approach to the realisation of a differential Colpitts oscillator is to connect the grounded capacitor in the feedback network of two single-ended Colpitts oscillators together in series. As the output signals are expected to be differential, it i ...
