Modelling, characterisation and optimization of substrate losses in RF switch IC design for WLAN applications

Abstract : This thesis is about characterization, modelling and optimization of substrate effects in integrated circuits, dedicated to WLAN applications.The objective of this thesis is to develop a new extraction methodology that takes into account all parasites; distributed RLCK models, electromagnetic effects, as well as substrate coupling.Substrate effects have been optimized through the development of a new insulation strategies using deep isolation isolation (DTIs).The circuit predictability has been improved thanks to the development of a new extraction methodology, based on a quasi-static approach taking into account the complete description of the BiCMOS process as well as the substrate loss, both capacitive and resistive effects.The validation of this methodology was evaluated by comparing simulation results with silicon measurements. The good correlation of the obtained results demonstrates the accuracy of this new methodology. This method also makes it possible to reduce the time to market thanks to the optimization of the simulation times.
