微加速度计启动漂移特性研究与实验
Characteristic Research and Experiment of Micro Accelerometer Startup Drift
摘要
Abstract
The bulk silicon micro accelerometer exists the problem of long start-up time and large start-up drift which can not satisfy the requirement of fast start-up application. In order to reduce the start-up time of the micro accelerometer, this paper researches on the start-up characteristic of the micro accelerometer, analyzes the heat generating and its conduct in the micro structure and the detection circuit and establishes the finite element model for the thermal analysis. A thermal resistor with the micro structure inside the chip package was fabricated to verify the analysis. Finally,with a series of experiment,it was proved that the thermal conduction and time drift are the main reason of the micro accelerometer startup drift.关键词
