Manufacturer:TI Description: The Motorola 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 processes (masking and etching). It can be modeled as a set of beams attached to a movable central mass that move be- tween fixed beams. The movable beams can be deflected from their rest position by subjecting the system to an accel- eration (Figure 2). As the beams attached to the central mass move, the dis- tance from them to the fixed beams on one side will increase by the same amount that the distance to the fixed beams on the other side decreases. The change in distance is a mea- sure of acceleration. The g--cell beams form two back--to--back capacitors (Fig- ure 2). As the central mass moves with acceleration, the dis- tance between the beams change and each capacitors value will change, (C = NA/D). Where A is the area of the facing side of the beam, is the dielectric constant, D is the distance between the beams, and N is the number of beams. 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. |
