    摘要

    A monolithic capacitance accelerometer is fabricated in 0.18μm ASIC-compatible CMOS MEMS technology and, with the assistant of universal sensing system being developed in the proposed work. The new approach combines the Dual-Chopper amplifier and Correlated Double Sampling to alleviate 1/f noise and DC offset. The total noise equivalent acceleration is 13.49ug/√Hz under 500 Hz. The tunable sensitivity can be adjusted from 324.8 mV/fF to 17807.11mV/fF (differential mode) by the fully-differential variable gain amplifier (VGA).
