Fully-integrated CMOS Probes for Magnetic Resonance Applications

Jens Anders

Techniques based on spin resonance effects are amongst the most powerful analytical methods in both modern chemistry and medicine. Recent years have seen a trend toward scaled-down detection coils, exploiting the fact that a reduction of the detector size ...

Self-Pulsation at Zero Absorber Bias in GaN-Based Multisection Laser Diodes

Nicolas Grandjean, Jean-François Carlin, Julien Dorsaz, Luca Alex Milo Sulmoni

We study the influence of pump current and absorber bias voltage on the pulse width and frequency of sustained pulsation in GaN-based multisection laser diodes. The observed frequencies and pulse widths range from 1.5 to 4.5GHz and 90 to 18 ps, respectivel ...

Offset compensation based on distributed Hall system architecture

Radivoje Popovic, Pavel Kejik

Integrated Hall devices have the great advantage, over other magnetic sensors, that they can be fully fabricated by a standard CMOS process. However they are known to have a relatively large offset (i.e. residual voltage at zero magnetic field). Techniques ...

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 ...

New approach for SOI pixel sensor

Louis Harik

Silicon on Insulator (SOI) is an interesting alternative to bulk silicon for the fabrication of integrated circuits due to its advantages with respect to the junction leakage, low switching noise coupling, high temperature immunity, low voltage and low pow ...

Bounds on the Sum Capacity of Synchronous Binary CDMA Channels

Pedram Pad, Vahid Aref

In this paper, we obtain a family of lower bounds for the sum capacity of code-division multiple-access (CDMA) channels assuming binary inputs and binary signature codes in the presence of additive noise with an arbitrary distribution. The envelope of this ...

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 ...

Noise analysis in super-regenerative receiver systems

Catherine Dehollain, Michel Declercq

The recent increase in the need for energy efficient wireless nodes have led to the study of various low power consumption receiver and transmitter architectures. The super-regenerative receiver architecture is one of the possible candidates for such a low ...

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- ...
