Texto completo da fonteThe aim of this thesis is the design of a wide-band RF analogue front-end for a cellular multi-standard and multiband receiver. The main limitation of receivers today is the need of external SAW filters to protect the LNA and mixer from out-of-band interferers. In this thesis we propose a new technique of positive feed-back which transposes the filters transfer function in RF. Thus, a selective RF filter is created in the LNA input to improve non-linearity performances of the receiver. This RF filter is also configurable in bandwidth and center frequency. An experimental prototype has been made in 65nm CMOS technology. The positive feed-back improves the LNA out-of-band IIP3 by 17dB. The center frequency is configurable from 1.3GHZ to 2.85GHz. Power consumption is of 30mW, while maximal NF is of 6.5dB

Texto completo da fonteExpectation Propagation (EP) is a powerful technique used in statistical inference to approximate complex probability distributions with simpler ones from the exponential family through moment matching. Recent works have demonstrated that its application in digital receiver design offers an attractive complexity-performance trade-off. By iteratively refining signal estimates via a message-passing approach, EP provides a robust framework for addressing challenges in digital communication systems, such as inter-symbol interference (ISI) in wideband channels. In this thesis, an EP-based Frequency Domain Self-Iterated Linear Equalizer (FD-SILE) is considered, comprising an equalizer, a soft demapper and a soft mapper. These components take advantage of EP for feedback within a self-iterating process. While the EP-based FD-SILE demonstrates favorable complexity-performance, its computational complexity remains prohibitive for hardware implementations, particularly for high-order constellations. In order to decrease this computational complexity, analytical simplifications are introduced for the soft mapping and demapping processes. These simplifications achieve substantial reductions in computational complexity while preserving bit error rate (BER) performance.As part of this thesis work, fixed-point versions of the simplified soft mapper and demapper are carried out to enable architecture design. Different architectures are designed for the modulation schemes of BPSK, QPSK, 8-PSK, and 16-QAM. These architectures are then optimized through pipelining, significantly reducing the number of clock cycles per frame. A flexible pipelined architecture, capable of dynamically switching constellations on a per-frame basis, is subsequently designed and implemented onto an FPGA device. Validation is conducted using a hardware-in-the-loop (HIL) configuration, which integrates a simulation environment on a computer with the FPGA-implemented architecture on a Zynq MPSoC platform

Texto completo da fonteThe demand of new multimedia services encourages the manufacturers to design receivers which use radio-software architecture and beamforming. A completely digital receiver is not yet feasible, or at great cost. A hybrid solution which associates in an optimal way analog and digital areas must be considered. A designing method was developed to specify the front-end of the system by taking into account the characteristics of the analog-to-digital converter, the beamforming and the desired signal to noise ratio at the output. A direct radiation planar antenna was developed so as to reduce the losses for the conversion of the broadband signal that requires a noise figure brought down to the input of the receiver the weakest possible, and to enable a distance inferior to /2 between the centers of phase of the element of the array so as to avoid the grating lobes in the case of important deviations of the beam

Texto completo da fonteIn the medical and surgical background, robotics can be of great interest for safer and more accurate procedures. Size constraints are however strong and complex movements may be necessary. To date, the design of dedicated non-conventional mechanisms is then a difficult task because of a lack of generic tools allowing a fast evaluation of their performances. This thesis combines higher-order continuation and automatic differentiation to adress this issue through the introduction of a generic modelling method and a generic formalism for mechanism design. Our contributions especially concern the development of numerical tools for the evaluation of the workspace, of the singularity localization and nature, and for a higher-order sensitivity analysis. These tools are evaluated on reference mechanisms

Texto completo da fonteAlzheimer’s disease (AD) is the most prevalent form of dementia in the aged population. So far, there is no way to halt or slow-down AD. Therefore, there is a constant need of developing novel therapeutic strategies.In recent years, adenosine A2A receptor (A2AR) has attracted a growing interest since it has been proved that this receptor is over-expressed during AD. Also, epidemiological studies showed that people consuming regularly caffeine-based beverages over a lifetime are substantially less likely to develop this disease. Indeed, A2AR antagonists improve memory performance as it reduces β-amyloid deposits and Tau-phosphorylation.Though several antagonists have been developed for the treatment of neurodegenerative diseases, current research efforts are focus on developing new antagonists with relevant ADME properties and a better efficacy. Based on a molecular modeling-guided design, we synthesised new A2AR antagonists with benzoxazole and quinazoline as central scaffold. Three molecules were selected and will be subject to evaluation on animal’s model

Texto completo da fonteThe design of circuits to operate at critical environments, such as those used in control-command systems at nuclear power plants, is becoming a great challenge with the technology scaling. These circuits have to pass through a number of tests and analysis procedures in order to be qualified to operate. In case of nuclear power plants, safety is considered as a very high priority constraint, and circuits designed to operate under such critical environment must be in accordance with several technical standards such as the IEC 62566, the IEC 60987, and the IEC 61513. In such standards, reliability is treated as a main consideration, and methods to analyze and improve the circuit reliability are highly required. The present dissertation introduces some methods to analyze and to improve the reliability of circuits in order to facilitate their qualification according to the aforementioned technical standards. Concerning reliability analysis, we first present a fault-injection based tool used to assess the reliability of digital circuits. Next, we introduce a method to evaluate the reliability of circuits taking into account the ability of a given application to tolerate errors. Concerning reliability improvement techniques, first two different strategies to selectively harden a circuit are proposed. Finally, a method to automatically partition a TMR design based on a given reliability requirement is introduced
