Full textFollowing the present day environmental issues and the necessary innovation challenges, along with the increasing demand of connected or embedded devices, power consumption is becoming a bottleneck for front-end signal processing circuits. In advanced microelectronics technology nodes, the power supply reduction helps naturally for lower energy dissipation. However, important added efforts are needed for high resolution designs. New design architectures with improved methodologies are necessary to reach performances which could be qualified as "Low Power" or "Ultra Low Power" circuits.In this thesis, our work focused primarily on the analog-to-digital converter (ADC) block, which often accounts for a huge portion of the total power consumption in an analog read-out chain. We explain why successive approximations architectures are still highly competitive. This work highlights recent algorithms and methodologies aimed at achieving the best compromise between resolution, speed and power consumption. We pay constant attention to the die surface. Three versions of ADCs were carefully modeled using MATLAB tools and then designed in 65 nm CMOS technology to evaluate their performances:- A 15-bit resolution SAR ADC with a sampling rate of 200 KS/s.- A 12-bit resolution SAR ADC at a sampling rate of 1.5 MS/s.- A 12-bit resolution SAR ADC based on a time-interleaved architecture, achieving a conversion frequency of 40 MS/s.For these three circuits, a segmented and split digital-to-analog converter (DAC) architecture is used, which significantly reduced the area and relaxed constraints on reference voltages. Calibration algorithms and dynamic element matching were employed to compensate the capacitors mismatch impacts. Additionally, we investigated a new generation of comparator leveraging significantly the reduced power consumption in contrast to conventional comparators, but at the cost of limited speed. Finally, after layout completion, the average consumption and surface characteristics are as follows:- For the 15-bit ADC: 8 µW consumption and an area of 40 µm * 2280 µm.- For the 12-bit ADC: 10 µW consumption and an area of 40 µm * 770 µm.- For the interleaved 12-bit ADC: 280 µW consumption and an area of 1125 µm * 771 µm.These layouts are designed with a shape allowing for column parallel applications

Full textThis Work presents a contribution to the design of asynchronous QDI (Quasi Delay insensitive) circuits for low power consumption. A quick study of the power estimation techniques will be shown. The methodology proposed will be presented in the chapter 2. This methodology uses 3 tools that perform the synthesis, optimization and the estimation of the asynchronous QDI circuits. The design of those circuits is done with a high level language for asynchronous circuits (CHP). The third chapter shows a study of different architectures to select the best one in terms of power consumption, speed and size. That chapter also shows a comparison between the equivalent synchronous circuits. In the final chapter, a technique for the reduction of the power consumption is presented. This technique changes the voltage of the circuit with a feedback control

Full textThis thesis concern the energy consumption studying of IEEE 802. 15. 4 networks (Low Rate-Wireless Personal Area Networks). This work contain two parts, in the first part, we propose a model from which we obtain an estimation of the power consumption in a wireless node while taking into account both MAC and PHY layers of this norm. We estimate this power consumption with a Markovien modelisation of the IEEE 802. 15. 4 MAC. The transition probabilities of the Markov chain are calculated using an interference and a traffic model. The synthesis of this work gives us a relation ship between nodes power consumption and each of the main parameters specified in the physical layer. In the second part, we explore the wireless routing possibilities in IEEE 802. 15. 4 networks. We propose a new routing protocol called MPSR (Multi-Path Source Routing Protocol). Through simulation, we demonstrate the robustness and the energy efficiency of MPSR and compare its results with classical routing protocols

Full textNear field RFID technologies use to embark loop antennas large enough to provide the amount of energy needed by the all the circuits they are interfaced with. Reducing the size of those antennas facilitates their integration into small sized objects and opens up the possibility of new applications. However, it also reduces the energy transfer capability of the system. In order to keep the same functionalities with this size reduction trend, it is clear that each important part of the integrated circuit need to have a higher efficiency. Although an overall optimization, ensuring an optimal contribution of each of all the parts of the system, is more fitting. In addition to this energy drop, the current applications create an increasing need of high data volume exchange and high data rates. The main objectives of thesis work are the optimization of the power transfer capabilities of 13.56MHz passive RF systems and the improvement of the communication circuits. A thorough study, to identify the key factors in RF power transfer, have been led. The ultimate goal being the design of an optimized system. For the communication aspect a discrete PLL, based on injection locking and gradient descent algorithm, was studied and designed. Thus introducing a new method of carrier recovery in this field. This PLL provides a synchronous clock to the system during OOK modulation and also a sine shaped clock for quadrature demodulation. This method was successfully tested on ASK and PSK modulated signals.Two chip have been design and manufactured, using STMicroelectronics 130nm technology for the power recovery system and UMC 55nm technology for the clock and data recovery system

Full textThis thesis work takes part in the connected objects theme, also known as the Internet of Things (IoT). It emerges from the Internet democratization since the early 2000's and the shift to highly mobile devices, made possible by the miniaturization of embedded systems. In this context, the energy efficiency is mandatory since today's projections are around tens of billions of connected devices in 2020. However for ease of deployment and usage, a large part of the data transfers in these networks is wireless, which implementation represents a significant part of the power consumption. Indeed, the energy efficiency question is addressed in general as a fine tuning of hardware architectures, which is often associated with a favorable technology evolution. Nevertheless, this design paradigm quickly reached its limits since it necessary implies a highly constrained sizing to be compatible with the worst operating conditions, even if they are not effective most of the time. It's typically the case with wireless communications since the radio channel is a medium characterized by a strong variability due to propagations effects and interferences. Thus, our study focused on the design of a communication chain whose link budget can be dynamically tuned depending on the actual signal attenuation, in order to reduce the system power consumption. The thesis has contributed to the design of a self-adaptive receiver dedicated to IEEE 802.15.4 standard, by proposing both a reconfigurable digital baseband architecture and an automatic control method of the operating mode. More precisely, the work relied on two approaches, the compressive sampling and the partial sampling, to reduce the data's size to process, decreasing the internal activity of arithmetics operators. In return, the demodulation processing needs a higher SNR, degrading in the same time the receiver sensitivity and thus the link budget. This solution, implemented in an STMicroelectronics CMOS 65 nm LP process, offers a low hardware overhead compared to conventional architecture with only 23,4 kgates. Thanks to the circuit physical model that has been developed, the power consumption for a packet demodulation is estimated to 278 uW when the baseband is fully activated. It can however be gradually decreased down to 119 uW, corresponding to a sensitivity reduction of 10 dB. Thus, the proposed digital baseband and its control loop save 30 % of energy in average in a typical use case

Full textConstruction of low, passive and positive energy buildings is generalizing and existing buildings are being renovated. For this reason, it is essential to use simulation in order to estimate, among other things, energy and environmental performances reached by these new buildings. Expectations regarding guarantee of energy performance being more and more important, it is crucial to ensure the reliability of simulation tools being used. Indeed, simulation codes should reflect the behavior of these new kinds of buildings in the most consistent and accurate manner. Moreover, the uncertainty related to design parameters, as well as solicitations and building uses have to be taken into account in order to guarantee building energy performance during its lifetime.This thesis investigates the empirical validation of models applied to a test cell building. This validation process is divided into several steps, during which the quality of the model is evaluated as far as consistency and accuracy are concerned. Several study cases were carried out, from which we were able to identify the most influential parameters on model output, inspect the influence of time step on the empirical validation process, analyze the influence of initialization and confirm methodology’s ability to test the model
