Full textWireless communications have evolved rapidly over the past twenty years. The design of these systems face some challenges: production cost, components integration techniques, size reduction, etc. Since many years, monolithic technology and specifically the manufacturing processes of silicon circuits (CMOS and BiCMOS) offer an opportunity to overcome such difficulties. Nowadays, they allow the integration of several RF and mixed functions on a single chip. However, the design of some RF functions is still a problem. This is the case of RF filters which constitute the essential elements of GSM telecommunications system. The demanded requirements by these filters lead to study solutions of active filters because passive structures (cavity, dielectric or SAW - Surface Acoustic Wave) do not allow better performance in term of insertion losses, selectivity, size reduction and frequency tuning. In this thesis, supported by an ANR contract (SRAMM project - Systèmes de Réception Adaptatifs Multimodes Multistandards), we were interested in the study of a new topology for active LC filter using Q-enhanced inductors. Our research analysis also consisted in defining a methodology for modeling three coupled inductors and using it to implement tunable LNA filter circuit useable in GSM3G system

Full textThis work concerns the conception of microwaves filtering functions at the same time band-pass, MMIC technology compliant, tunable and differential. The main objective is to realize filtering structures compatible with opportunist radio. The second objective is to demonstrate that ferromagnetics inductors improves the performance of such devices. Commersialised RF receivers are deadlocked due to their topologies and used components (SAW filter, LNA for example). We put forward new integrated circuits : filtering LNA and 1, 2 and 3 poles filters usable in fully frequency tunable receivers. These circuits are Q-enhanced resonator based. They have a continuous frequency and bandwidth tunability over an octave. The observed results at first for filtering LNA mixe wide tunablility, gain and low noise figure on a unique MMIC circuit. This contribution is a first step toward opportunists receivers

Full textThis thesis concerns the design of tunable filter devices that can switch theirs characteristics from one standard to another in order to reduce the congestion of emission/reception chain of multi-standard systems. The most commonly used filters are acoustic filters. Indeed, these filters are difficult to be integrated in silicon technology and they remain one of the most bulky passive devices of the RF front-end. In addition, they don’t achieve good performance in insertion loss, frequency selectivity and tunability. Therefore, alternative solutions are at the origin of this thesis. An active filter is considered with the possibility of adjusting the resonance frequency: the resonant frequency of the Wifi system and the resonance frequency of the Zigbee system. Moreover, another solution is proposed in the last chapter, which consists to achieve a dual band structure of integrated active filter. This solution has the advantage to simultaneously collect data provided from the operating systems located in the two specified frequencies bands. Simulations and measurements validate the results of the realized circuits

Full textDue to the evolution of wireless systems and data rate, it is necessary to increase microwave operating frequencies, especially in space industry. Optimization of existing circuit topologies are always not enough and therefore, we need to synthetize new circuits. Unfortunately, most of the existing synthesis methods, including in CAD softwares, are only based on lossless passive component models. With the increase of operating frequency, we need to take the effect of losses in the passive component models during synthesis. This thesis introduces a new synthesis and design method for low noise integrated circuits(low noise amplifier and mixer). Lossy passive component models from foundries, connecting wires, junctions and co-design (amplification and filtering or mixing and filtering)are included. The design procedure was validated by simulations and measurements

Full textUltra Wide Band (UWB) systems are a new wireless technology capable of transmitting high data rate over a wide frequency spectrum for short distances (< 20 m) for wireless applications. The Power Spectrum Density (PSD) of the emitted signals must be as low as -41. 3 dBm/MHz. In February 2002, the Federal Communication Commission (FCC) has allocated a band from 3. 1 to 10. 6 GHz for UWB communications. From that time, some differences appear depending on the country. Among all the various transmission techniques using UWB labelled modulations, we study the Multi-Band-Orthogonal Frequency Division Multiplexing (MB-OFDM) modulation which has been proposed by the European Computing Machineries Association (ECMA) in 2005. However, the efficiency of Impulse Radio (IR) was pointed out. In this way, an original topology known as Multi-Band On-Off Keying (MB-OOK) is also presented. In this thesis, we develop a System Simulation Tool (SST) to analyze the performances of UWB-OFDM system. The impact of the Radio-Frequency (RF) front-end and Low Noise Amplifier (LNA) non-linearity is studied on the Bit Error Rate (BER) of the overall receiver. In the MB-OOK transmission chain, different filters are introduced. BER is studied in order to know which properties of the filters have the main impact on the MB-OOK transmission performances. The optical domain can also be advantageously used to provide broadband optical UWB signal processing functions. Broadband Radio-over-Fiber (RoF) networks are raising great interest to provide both low cost optical intra-building distribution and signal processing of UWB signals. We investigate, from Error Vector Magnitude (EVM), optical transmission and frequency up-conversion of UWB-OFDM signals. In this proof of concept, a specific study is carried out to evaluate the capability to up-convert a MB-OFDM signal, and the impact of the Electronic/Optical (E/O) transceiver on the performance of the UWB-over-fiber system

Full textAu travers des nombreuses techniques de transmission ULB, nous étudions la modulation multi-bandes à répétition en fréquence orthogonale (MB-OFDM) qui a été proposée par l'European Computing Machineries Association (ECMA) en temps que standard en 2005.L'efficacité des signaux Impulsionnel Radio (IR), précurseur à l'ULB, a cependant été montrée. Nous présentons à ce titre une topologie originale nommée Multi-Bandes On-Off Keying (MB-OOK).
Dans le cadre de cette thèse, nous développons un outil de simulation système (SST) afin d'analyser les performances d'un système ULB-OFDM. Nous étudions l'influence sur le taux d'erreur binaire (BER) des non-linéarités du front-end de réception Radio-Fréquence (RF) et de l'amplification de puissance faible bruit (LNA) dans une chaîne de transmission globale.
Dans le cadre des systèmes MB-OOK, différents types de filtres sont envisagés. L'impact sur le BER est étudié afin de connaître les propriétés prédominantes des filtres sur les performances de transmission.
Le domaine de l'optique peut également être avantageusement employé dans des processus de transmission ULB. Les réseaux larges bandes radio sur fibres (RoF) présentent de nombreux intérêts pour fournir à moindre coût la distribution du signal mais également la possibilité de pouvoir le traiter directement. Dans ce sens, Nous évaluons les possibilités de convertir fréquentiellement des signaux de type ULB-OFDM, ainsi que d'évaluer l'impact de transmetteurs Electrique/Optique (E/O) sur les performances d'un système ULB sur fibre à partir des valeurs du vecteur d'erreur d'amplitude (EVM).
