Abstract
Mathematical model of sensitive structures and detection principle of Sigma-Delta accelerometer are analyzed in this paper, and then an accelerometer with SNR 107dB is designed using MATLAB, the stability of which is analyzed based on root locus plot. When input is small than-3dBFS, the system is unsaturated. The poles and zeros of accelerometer noise transfer function are then analyzed and the feed-forward coefficient and local feedback coefficient are optimized, achieving a higher SNR of 112.1dB. At last, the circuit-level simulation is conducted and in-band noise level is about-140dB.
