Full textProduction testing of Radio Frequency (RF) integrated circuits is costly due to the high cost of the test equipment and the long test times. In order to reduce this cost, DfT (Design-for-Test) and BIST (Built-in Self-Test) techniques are currently under research. However, these techniques are not yet considered by the Semiconductors Industry since their test quality is not fully demonstrated. In this thesis, the design and the evaluation of a BIST technique for RF Low Noise Amplifiers (LNAs) is considered. The BIST technique uses integrated sensors for measuring current consumption and output power of the LNA. The output of theses sensors are DC or low frequency signals that can be treated with low-cost test equipment. The BIST quality is evaluated using test metrics that consider device process deviations, catastrophic and parametric faults. To obtain an estimate of test metrics with an accuracy of ppm (parts-per-million), a first sample of the LNA is obtained by Monte Carlo electrical simulation. Next, a statistical model of the joint probability density function of LNA performances and test measures is obtained. Finally, a million synthetic instances of the LNA is generated by sampling the statistical model. This large sample is used to set the test limits of the embedded sensors and for computing test metrics. The BIST technique has been validated for a ST Microelectronics 0. 25 ¸tm BiCMOS LNA using different statistical models. The validation of the technique at the layout level has also been considered in order to get results as close as possible to the production test of a real LNA population

Full textThis 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

Full textThe high bandgap technologies are being increasingly popular for over a decade because of their natural ability to perform electronic functions operating at high power, high temperature and high frequency. Among these technologies, one based on the heterostructure AlGaN / GaN is most mature currently at microwave frequencies. The use of a heterojunction InAlN / GaN is an attractive solution to increase the operation frequency of these devices and thus to realize circuits operating at millimeter waves. The first part of our work is devoted to the study of various InAlN/GaN technology developed by III-V Lab. It helped to highlight the different gate current conduction mechanisms through an analysis of the leakage current and the C-V measurements of the Schottky junction. Measures in small-signal showed the frequency dispersion of the output conductance and the extrinsic transconductance until 1 GHz. We have proposed broadband analytical models to take into account the dispersion phenomena during the circuit design. A second part consisted of the study of the background noise in the InAlN / GaN transistors. The low-frequency noise characterizations and modeling revealed and confirmed trapping / detrapping mechanisms observed in the electrical study. The study of highfrequency noise has assessed the technological developments of this sector and to know the optimal conditions for the design of LNAs. In the last part, hybrid low noise amplifiers have been made from these devices deferred flip-chip on alumina to demonstrate the potential of this technology in Ka-band. Single stage amplifiers have been designed especially for stress testing, and have a gain of 5. 6 dB and a noise figure of 3. 1 dB at 29. 5 GHz. The simulations carried out on 3 stages amplifiers indicate interesting performances in terms of gain (20 dB) and noise figure (3 dB) compared to those obtained in the literature on the GaN based devices

Full textThe recent enthusiasm for the Internet of Objects as well as for satellite communications leads to the need for high-performance radio-frequency (RF) communication systems. In order to meet the constraints of the mass market, these systems must be compact and be as low power as possible. Beside, they are expected to address multiple communication standards and to adjust their performance to the environment, still in order to reduce the size and the power consumption. Currently, many works focus on the development of low-noise amplifiers (LNA), the most critical block of RF receivers. To address this purpose, the goal is to design multi-mode and multi-standard receivers. Hence, LNAs require design flows that can adapt to the different technologies and topologies in order to meet any given set of specifications. This thesis aims at the development of simple and accurate design methodologies for the implementation of low-noise amplifiers.The first proposed methodology is dedicated to the implementation of a LNA in COTS technology for spatial applications. This LNA offers a broadband matching to address several standards. It is designed to be part of an RF receiver for nano-satellites. Thus, the latter is first studied in order to determine the specifications based on the standards of the targeted applications.The second methodology is dedicated to the implementation of LNAs in CMOS technology for any kind of applications. This methodology is first illustrated with basic topologies and then applied to an highly linear inductorless LNA. The design methodology also enables a fair comparison between the topologies and also CMOS technologies, even the most advanced ones such as the 28 nm FDSOI.Finally, reconfigurability is added to the inductorless LNA, to address several standards while retaining the optimum sizing given by the previously introduced methodology. Indeed, the size and polarization of each transistor are digitally controlled in order to adjust the LNA's performance to a given standard. Furthermore, the study of N-path filters combined with the proposed LNA is explored to improve the linearity of the circuit
