Texto completoThis PhD thesis was carried out in the framework of a contract CIFRE between the GREYC laboratory and the company Inphynix. The objective is the study and development of high performance magnetometers, based on search coils and associated transimpedance amplifier with a perspective of simultaneous measurement of both Electric E and Magnetic H fields. The magnetometer specifications were a high bandwidth, a high dynamic range and a small volume occupancy. A theoretical and experimental study of compact search coils dedicated were performed. The spatial resolution for search coils with different geometrical forms was studied. Differential current amplifiers and transimpedance amplifiers optimized for this application were studied especially for differential signal mode transfer and noise. An original differential search coil based magnetometer, made of coupled coils, operating in flux mode and connected to a differential transimpedance amplifier has been developed. It was shown that this structure is better than two separated coils in terms of volume occupancy, spatial resolution, noise and low cut-off frequency. The structure of an original mixed E-H field sensor and its amplifier has been defined. Key words: Search coil sensor, Magnetometer, Transimpedance amplifier, Differentiel current amplifier, Spatial resolution, mixed E-H field sensor

Texto completoThis work deals with the study on high frequency noise when components and active circuits are working under large signal conditions. It could be the case for broadband receivers fitted with low noise amplifiers, which are desensitized by blocking signals. Mixers and oscillators are also under consideration. Firstly, a behavioural modelling is described and allows us to point out the interaction of white noise with a sinusoidal signal. The theoretical model is compared to several conditions of operation, and we obtained satisfying agreements. Many amplifiers are tested and compared; at least, the behavioural modelling is used to study their additive noise. The second part is dedicated to measurement techniques we have developed for this work. We are capable to measure noise figure and noise parameters of microwave active devices functioning with strong power signals. We also propose an original method which provides the four noise parameters of discrete components or amplifiers working under large signal condition. The results we have found are indirectly compared to residual phase noise measurements. After all, the last part affects the design of low noise amplifiers working under nonlinear condition. Various silicon bipolar transistors have been characterized, and a figure of merit have been set in order to find the best component taking into account noise figure and linearity. Finally, simulations and experimental results demonstrate the interest of designing circuits working under strong nonlinear regime

Texto completoAdvanced silicon technologies, such as BiCMOS B55X from STMicroelectronics, which target fT/fmax cutoff frequencies above 400 GHz, are enabling the development of silicon circuits in the 140-220 GHz range (G-band). To validate these technologies, microwave characterization methods for on-wafer measurements are essential to extract the figures of merit of transistors, passive circuitry and associated parasitics. However, broadband circuits like noise sources (NS), noise receivers and impedance tuners at these frequencies are very incompletely covered by the market offer. Previous research demonstrated that embedding measurement functions directly onto silicon in BiCMOS B55 technology is possible, but this in-situ approach or built-in self-test (BIST) has certain limitations, particularly in terms of the silicon surface allocated to the test circuits alone and also because embedded BIST instrumentation cannot be used for another technology.This thesis broadens the applicability of measurement instrumentation beyond the B55X process and aims to reduce testing costs by transitioning from BIST to smart probes. This new approach focuses on integrating measurement functions into compact systems placed as close as possible to the measurement probes for ex-situ measurements.Building on earlier research achievement as part of a previous thesis, the first-ever packaged NS based on SiGe BiCMOS 55-nm technology was developed and characterized in two distinct configurations. In a first flavor, on-wafer noise measurements yielded an extracted excess noise ratio (ENRav) level of 37 dB in the 140-170 GHz. In an alternative approach, the NS was packaged in a split-block with a WR5.1 flange termination for connection to commercial passive probes, achieving an ENRav level of up to 25 dB in 140-220 GHz corresponding to a 12 dB ENR reduction when compared to the on-wafer measurements.To improve on this work, a key achievement of the present thesis is the development of Ground-Signal-Ground (GSG) probes for on-wafer measurements fabricated using femtosecond laser micromachining with a resolution between 5-10 µm. These probes made from 100 µm thick Schott AF32 glass substrate bonded to a 10 µm thick nickel sheet, demonstrate improved mechanical durability and electrical performance. Nickel was chosen for the tip contacts due to its mechanical hardness and superior electrical properties, which minimize contact resistance and extend probe lifespan. Mechanical testing revealed that while glass-only probes failed at a contact force of 196 mN, the nickel-glass probes withstood forces up to 667 mN. Additionally, these probes achieved low-resistance electrical contacts (0.05 Ω above 6 mN), as verified through four-wire measurements on a single contact point.Furthermore, this research introduces a novel substrate technology that integrates an amplified NS B55X chip onto a glass interposer to reduce dielectric and transition losses. Using femtosecond laser micromachining, the interconnects are precisely structured, allowing the integration of the NS chip on the same substrate used to manufacture the coplanar probing tips, with the advantage of simplifying the signal propagation path. This system achieved a tunable ENRav level of up to 29 dB in the 140-170 GHz range, with constant output impedance matching better than -12 dB across the entire frequency band. This innovation allows for the integration of the GSG probes with the NS to perform on-wafer noise measurements.This research opens new possibilities for cost-effective, scalable millimeter-wave active probes for on-wafer measurements. Their adaptable design makes them suitable for diverse applications, advancing circuit characterization and high-frequency semiconductor testing

Texto completoquasiparticules, ou, de manière plus intéressante, est du à la réflexion d'Andreev. La théorie du blocage de Coulomb dynamique est utilisée pour calculer le courant continu qui passe dans le circuit de détection, procurant ainsi une information sur le bruit à haute fréquence. Dans la deuxième partie de cette thèse, la source de bruit est connue : elle provient d'une barre de Hall avec un contact ponctuel, dont les caractéristiques de courant-tension et de bruit sont bien établies dans le régime de l'effet Hall
quantique fractionnaire. Un point quantique connecté à des bornes source et drain, qui est placé au voisinage du
contact ponctuel, acquière une largeur de raie finie lorsque le courant fluctue, et se comporte comme un
détecteur de bruit de charge. Nous calculons le taux de déphasage du point quantique dans le régime de
faible et de fort rétrodiffusion, tout en décrivant l'effet de l'écrantage faible ou fort de l'interaction
Coulombienne entre la barre de Hall et le point quantique.
