Full textThe constant increase in the number of sensors in modern cars, fulfilling advanced driving assistancefunctions, places the automotive radar as an essential element in today’s and tomorrow’svehicle. This tendency is motivated in the long term by the development of autonomous vehicles.The industry considers moving the automotive radar product from the current standard around80 GHz to a new frequency band around 140 GHz. This increase in the operation frequency wouldenable more compact sensors while maintaining and even improving the sensor accuracy thanksto MIMO applications. This work aims to assess the feasibility of a radar receiver at 140 GHz.A first part of this work is dedicated to the development of design tools and models which facilitatethe implementation of millimeter wave circuits. First, a design methodology for impedancematching networks based on integrated transformers is presented. Thanks to their numerousadvantages in addition to their impedance matching capability, they will be used in all thefollowing development of this work. Then, a complete model of the multi-harmonic behaviorof passive N-path circuits and more particularly N-path mixers is proposed. Their benefits interm of noise, current consumption and linearity make them suitable for the implementation of140 GHz automotive radars.A second part of this work is focused on the implementation of multiples RF front-ends forradar receivers, based on a mixer-first architecture. Two solutions are first proposed which fullyexploit the advantages of the modeled mixers at the considered frequency. A fundamental solutionis proposed which complies with the long-range radar applications. A sub-harmonic alternativewith a slightly reduced range is then presented. It would enable significant savings on the chiparea and the current consumption, answering to a market demand for low-cost radar productsthat can be embedded in large number inside one vehicle.Finally, a novel type of passive mixers, called bottom-plate mixer is studied to design twoadditional radar receivers front-ends. These mixers keep the advantages of the traditional N-pathmixers while also presenting a high voltage gain. A fundamental receiver is proposed, based onan existing topology at RF frequencies only, that addresses the constraints for the 140 GHz radarapplication. A second sub-harmonic receiver is designed with a novel topology developed in thiswork, which complement the first receiver. These two front-ends allows a longer detection rangefor the radar module

Full textThe world of transportation is currently experiencing a revolution towards complete automation. However, this automation depends on the creation of new communication systems with high data rates and low latency. Thanks to the development of 5G, new scenarios such as vehicle-to-vehicle communication or communication between vehicles and the rest of the infrastructure have become possible. The same applies to more complex environments, such as the railway sector, where a transformation in communication systems is underway with the study of a new communication standard, FRMCS. However, to achieve such systems, a deep understanding of the behavior of the radio propagation channel is essential. To meet this need, at IMT Atlantique, a channel sounder has been developed, allowing long-term measurements for dynamic scenarios in vehicular environments. This sounder has been installed in various environments to be tested under in situ conditions before being used in a measurement campaign in the railway sector. From these measurements, large and small-scale parameters are calculated for different environments, following a scenario similar to the architecture proposed by 3GPP. Finally, these results are discussed and compared with the models provided by the same 3GPP

Full textThis work focuses on the design of on-silicon mm-wave Reflection-Type Phase Shifters (RTPS) with Oscillation-Based Test (OBT) capabilities. For more consistency, a single technology was considered, the STM 55-nm BiCMOS. First, the theory and practical implementations of 3-dB couplers is discussed. Particular attention is brought to the Coupled Slow-wave CoPlanar Waveguide (CS-CPW) topology, due to its good performance. Using this topology, the measurements of two 3-dB couplers are reported: (i) a 120-GHz, and (ii) a 185-GHz coupler.Next, the existing topologies of integrated varactors are discussed. Measurement results are reported for an Inversion-mode MOS (I-MOS) varactor from 1 up to 325 GHz. Additionally, the Common-Source MOS (CS-MOS) varactor architecture is proposed and measurement results from 1 to 145 GHz for this architecture are reported.Then, the theory of RTPS is presented and CS-CPW-based couplers together with Accumulation-mode MOS (A-MOS), I-MOS and CS-MOS varactors are used for the design of four RTPS. The measurement and simulation results of these RTPS, with central frequencies ranging from 60 to 200 GHz, are presented.Subsequently, the theory and measurement results of the OBT on an integrated 60-GHz RTPS are discussed.Finally, a mm-wave TRL calibration compaction technique is described using machine-learning tools

Full textIn response to the flourishing market demands for the new generation of IoT devices, thiswork addresses the design and optimization of Low Noise Amplifiers (LNAs). The LNAsserves as the main building block of low-power LNA-first sub-6GHz receivers dedicated to5G Long-Term Evolution for machines (LTE-M) and Narrowband IoT (NB-IoT) cellularstandards. Recognizing the escalating challenges in ultra-low power IoT device connectivity, the significance of optimizing LNAs lies in enhancing overall receiver performanceand meeting the strict low noise and reduced power budget requirements of LTE-M andNB-IoT applications. Besides, it requires the utilization of cost-efficient, high-performing,and extensively integrated technology for Very Large Scale Integration. In this thesis, weemploy the 28 nm FD-SOI CMOS technology provided by STMicroelectronics.To improve power efficiency, the LNA is designed using a comprehensive analyticalmethodology. This methodology leverages the transistor inversion level as a key designparameter, providing insights into the design space. Employing a proposed simple 6-parameter advanced compact model (ACM) introduced in this work, applicable acrossall transistor regions and operation regimes, the methods enable preliminary LNA sizingthrough analytical equations. This simple model, an adaptation of previous ACM versionsaccommodating various physical parameters, is made suitable for both bulk and FD-SOItechnology, incorporating a fourth terminal.The primary contribution lies in the design of a wideband, low-noise sub-6GHz tunable multimode inductorless LNA, utilizing an active gm-boosting Common-Gate (CG)architecture. Tunability is achieved through discrete coarse mode selection and continuous fine-tuning the back-gate of FD-SOI CMOS technology, showcasing the adaptabilityof body-bias for finely tunable architectures, specifically addressing the dynamic demandsof IoT environments.The transistor model, coupled with the analytical LNA description, guides the designalgorithm, exploring various performance trade-offs against the specified requirements.Implemented in STMicroelectronics’ 28 nm FD-SOI CMOS Technology with an activearea of 0.0059 mm2, the measured performance demonstrates over 30 dB voltage gainwith a dynamic range exceeding 20 dB across modes for a frequency range of 400 MHzto 5 GHz. The noise figure (NF) varies from a stringent value of 1.8 dB to 7 dB, while the Input-referred third-order Intercept Point (IIP3) spans from -24.5 dBm to -6.5 dBmbased on the selected mode. The maximum power consumption is 1.86 mW from a 0.9 Vsupply. Fine-tuning the LNA performances across modes achieves extensive coverage ofthe design space.Furthermore, the proposed design methodologies are applied to different LNA architectures, including Resistive feedback common-source, common-gate, and gm-boost common gate LNAs, showcasing the simplicity and applicability of the analytical approach in addressing diverse design scenarios. This paves the way to future energy-efficient implementations targetting ULP ULV IoT receiver front-end solutions

Full textMobile communications are in constant race to meet the demands of the users, especially in the terms of the amount of data they want to use. The introduction of the 5G NR (New Radio) will exceed the current limits but it needs technological breakthroughs to achieve its goals. To achieve the promises of the new 5G NR communication standard the electronics industry is interested in to develop new key components for tomorrow. The objective of this thesis work has been to design two key components to respond to the different future developments of the mobile devices. Therefore a frequency agile filter for frequencies below 6 GHz and a low cost antenna array around 28 GHz for 5G NR have been designed, manufactured and tested

Full textNowadays, High Electron Mobility Transistors (HEMTs) in Gallium Nitride (GaN) take the lead in power amplification at microwave frequencies. Most of the studies and developments on those HEMTs concern AlGaN/GaN structures but alternative transistors with an InAlN barrier, which reduces the strain in the crystal lattice of the whole structure, are investigated by few laboratories. This thesis presents some advanced studies on the new InAlN/GaN HEMT developed by the III-V Lab, focusing on the trapping phenomena induced by defects inside the crystal structure. A new method for the characterization of these defects, based on low-frequency S-Parameters measurements, is proposed. Furthermore, a non-linear electro thermal model including trapping effects for an InAlN/GaN HEMT is detailed and used to design a MMIC power amplifier for Ka-band applications

Full textThe work in this thesis has been funded by the French FUI project MASS-START (2017-2020). The project aims at the integration of 5G compatible baseband and radio subsystems into an Over-Air-Interface-based 5G terminal and gNodeB demonstrator, and the antenna array for end-to-end Multiple Input Multiple Output link experimentation. The scope of the thesis concerns the design and assessment of antenna systems that are to be used in the project.At 5G Frequency Range 1 band, the work concentrates on the development of a methodology to design antenna with a matching circuit for mobile terminals with limited area. The bandwidth limitation is evaluated using Quality-Factor. A Particle Swarm Optimization algorithm is proposed and examined in different antenna designs for mobile terminals. The final design demonstrates a system with three non-resonating coupling elements covering most of the sub-6GHz bands of 5G. At 5G Frequency Range 2 band, more precisely band n258 of Europe, different types of array antennas are studied. The work first checks two types of feeding for a patch antenna that can be integrated into Printed Circuit Board to have a low profile antenna and ease the fabrication procedure. The designs are later fabricated and experimentally evaluated. With a Millimeter-Wave array at hand, we proceed a measurement campaign in which the effects of the user's finger at close proximity of the antenna are evaluated. The losses due to absorption, reflection, diffraction are quantified and compared with numerical estimations in literature. A system of multiple end-fire arrays placed at different locations in a terminal is also studied showing the compromising effectiveness if one array is severely blocked

Full textThis research work has been motivated primarily by the significant advantages brought about by the UTBB FDSOI technology to the Low power Analog and RF applications. The main goal is to study the dynamic behavior of the UTBB FDSOI MOSFET in light of the recent technology advances and to propose predictive models and useful recommendations for RF IC design with particular emphasis on Moderate Inversion regime. After a brief review of progress in MOSFET architectures introduced in the semiconductor industry, a state-of-the-art UTBB FDSOI MOSFET modeling status is compiled. The main physical effects involved in the double gate transistor with a 7 nm thick film are reviewed, particularly the back gate impact, using measurements and TCAD. For better insight into the Weak Inversion and Moderate Inversion operations, both the low frequency gm/ID FoM and the proposed high frequency ym/ID FoM are studied and also used in an efficient first-cut analog design. Finally, a high frequency NQS model is developed and compared to DC and S-parameters measurements. The results show excellent agreement across all modes of operation including very low bias conditions and up to 110 GHz
