Analysis on Modeling and Simulation of Low Cost MEMS Accelerometer ADXL202

In this paper, we describe the simulation of low cost MEMS accelerometer ADXL202 model to gain the required output using MATLAB/SIMULINK. It contains theory of operation of ADXL202 and its applications. In this paper, the design procedure for using the ADXL202 with a duty cycle output is described and it includes selecting a duty cycle period and a filter capacitor. A proper design will take into account the application requirements for bandwidth, signal resolution and acquisition time. It describes the filter capacitor selection of ADXL202 to reduce the noise and improve the resolution of accelerometer. Finally, simulation results for desired output signals for the system and noise reduction are described. Keywords— Modeling, Simulation, Accelerometer ADXL202,
