Méthode de conception des systèmes différentiels RF utilisant le formalisme des modes mixtes


These research works aim to develop analytical tools for the analysis and design of differential systems. While the use of these circuits in RF reception/transmission chains is increasingly growing, there is no accurate method to study their stability. Therefore, the first part of this work is to develop a CAD tool which can be rigorously use to investigate the extrinsic stability of linear differential systems. The second part refers to the design of a three-ports differential component for space telecommunication application. Indeed, for system requirements, it is often necessary to convert a differential access into a single-ended access. This operation allows the differential device to communicate with other components in the system. For this purpose, a broadband differential active balun is designed using BiCMOS technology. Differential measurements are performed and the results are compared to the initial performances of the spatial application technical specifications
