摘要
The implementation and characterization of a high sensitivity silicon-on-insulator (SOI) capacitive microaccelerometer with sub-25mug resolution is presented. The in-plane accelerometers were fabricated on 40mum thick SOI substrates using a two-mask, dry-release low temperature process comprising of three plasma etching steps. The fabricated devices were interfaced with a high resolution, low noise and low power switched-capacitor integrated circuit (IC) fabricated in a 2.5V 0.25mum N-well CMOS process. The measured sensitivity is 0.2pF/g and the output noise floor is 20 mugrootHz. The total power consumption is 3mW.
