FUNCTIONALITY
1.1 Sensor element
The ThELMA process is utilized to create a surface micro-machined accelerometer. The technology allows car-
ry out silicon structure on suspension, the structure are attached to the substrate in few points called anchor
and free to move on a plane parallel to the substrate itself. To be compatible with the traditional packaging tech-
niques a cap is placed on top the sensor element to avoid the molding goes between the elements making the
sensor useless.
The equivalent circuit for the sensor is shown in the below figure; when a linear acceleration is applied, the proof
mass displaces from its nominal position, causing an imbalance in the capacitive half-bridge. This imbalance is
measured using charge integration in response to a voltage pulse applied to the sense capacitor.
The nominal value of the capacitors, at steady state, is few pF and when an acceleration is applied the maximum
variation of the capacitive load is few tenth of pF.
