Abstract :
This paper presents the packaging and residual stress effects on three-axis silicon-on-insulator (SOI) micro-electro-mechanical system (MEMS) accelerometer by using finite element method (FEM). The 3D FEM model was established and the resonance frequency was obtained by modal analysis method. This paper also developed a simple compensation model for trimming the offset of capacitance differentiation by measuring resonance frequency. It can be trimmed by adjusting application-specific integrated circuit (ASIC) gain. The capacitance differentiation offset which is caused by packaging effect can be effectively compensated to the standard capacitance differentiation.
