A Simulation-Based Coupling Path Characterization to Facilitate Desense Design and Debugging
Coupling path characterization is the most critical part of the simulation-based method to investigate desense issues. This paper introduces the workflow to model and validate the coupling path. The workflow is then embodied in a practical case where the GPS system of a phone is severely desensitized by the camera flex. The coupling path between the camera flex and the GPS antenna is successfully characterized and validated by measurement. The obtained coupling path model is further utilized to study factors that potentially affect the noise coupling from the camera flex to the GPS system. Knowledge of these factors facilitates desense design and debugging. Design guidelines are proposed based on the coupling path model.
