The book "Design of a Capacitive based Closed-Loop Displacement Sensor" by Johan Schabbink offers a comprehensive analysis and detailed description of the development of capacitive sensors within a closed-loop system. It addresses the decomposition of the fundamental concept into various system elements, with a specific model created for each element to describe its behavior. These models are then implemented into the physical components of a MEMS system. The author places particular emphasis on optimal placement and available space during development to ensure maximum resolution. A central theme of the book is the integration of all physical MEMS parts into a complete structure, with the controller highlighted as a crucial element, as it ensures the stability of the system during operation. The balance between bandwidth and stability is another important aspect considered in the design process of the controller.
