Novel MEMS fully differential capacitive transducer design and analysis

Abstract

This paper details the design and analysis of a novel MEMS fully differential capacitive sensor which can be used to measure the parameter related to force changes, such as pressure or acceleration. This MEMS model uses a new structure to get extremely high resolution of 11.6fF/KPa. Further it has a good level of linearity as regard changes in capacitance as a function of force change.
