Stability of nonlinear high frequency amplifiers

Participants : Sébastien Fueyo, Jean-Baptiste Pomet, Laurent Baratchart [APICS project-team APICS (FACTAS as of 2018)] .

Sébastien Fueyo's PhD is co-advised between McTAO and APICS on this topic. The problem is presented in section 4.4.

Starting from infinite dimensional time-domain models for these devices, we obtained full justification (with some possible obstructions) to the prediction of stability through transfer function identification on academic examples of simple circuits, and are working on generalisations. A preliminary presentation will be given at a local conference, Université Côte d'Azur Complex Days, in January, 2018.
