Abstract:
In order to optimize front-end topologies of capacitive sensors precise knowledge of the coupling capacitances is important. These capacitances are not easily accessible by means of measurement without significantly altering them, and therefore a numeric method for determining them is advantageous. In this paper we use a Boundary element formulation for this task. Certain aspects of numerical accuracy of the formulation used are addressed. Results from simulations and optimizations are presented and compared with experimental results for validation of the approach.
