摘要

为了改善电容式微机电系统（Micro-Electro-Mechanical Systems，MEMS）硅麦克风输出的非线性和温度漂移，本文在调研了相关传感器输出校准相关算法的基础上，提出了一种基于Pade近似的新型校准算法，具有较高实用性，已成功应用于国产高性能MEMS麦克风传感器中.该算法中，首先利用Pade近似对硅麦克风输出数据进行处理，以改善交叉灵敏度和跳跃点的影响；并利用一种精度拟合和线性回归的方法进行二次计算，以达到提高输出的校准精度的目的.在相对湿度50

的环境下，精度可以从6

FS提升到1.2

FS.与目前主流的相同精度的多项式拟合校准算法相比，本文使用的算法消耗的计算内存减少了约14%.该算法对于其他传感器或电路输出响应优化具有重大参考意义.

Abstract

In order to improve the nonlinearity and temperature drift of the output of the condenser micro-electro-mechanical systems (MEMS) silicon microphone

Based on the relevant algorithms of the current sensor output calibration strategies

and proposes a novel calibration algorithm based on the Pade approximation is proposed and testified

which is adopted in practical industrial application with high practicability. In a humidity environment with RH 50%

the accuracy of MEMS sensor can be improved from 6%FS to 1.2%FS. Compared with the current mainstream polynomial fitting calibration algorithm with the same accuracy

the algorithm used in the paper consumes about 14% less computational memory. The algorithm has great reference significance for the optimization of output response of other sensors or circuits.
