Manufacturer:MURATA Description: The Freescale Semiconductor accelerometer is a surface-- micromachined integrated--circuit accelerometer. The device consists of a surface micromachined capaci- tive sensing cell (g--cell) and a CMOS signal conditioning ASIC contained in a single integrated circuit package. The sensing element is sealed hermetically at the wafer level us- ing a bulk micromachined cap wafer. The g--cell is a mechanical structure formed from semicon- ductor materials (polysilicon) using semiconductor pro- cesses (masking and etching). It can be modeled as two stationary plates with a moveable plate in--between. The center plate can be deflected from its rest position by sub- jecting the system to an acceleration (Figure 2). When the center plate deflects, the distance from it to one fixed plate will increase by the same amount that the dis- tance to the other plate decreases. The change in distance is a measure of acceleration. The g--cell plates form two back--to--back capacitors (Fig- ure 3). As the center plate moves with acceleration, the dis- tance between the plates changes and each capacitors value will change, (C = A/D). Where A is the area of the plate, is the dielectric constant, and D is the distance be- tween the plates. The CMOS ASIC uses switched capacitor techniques to measure the g--cell capacitors and extract the acceleration data from the difference between the two capacitors. The ASIC also signal conditions and filters (switched capacitor) the signal, providing a high level output voltage that is ratio- metric and proportional to acceleration. |
