【Abstract】 The signal detection circuit is designed,join with the capacitive accelerometer,later is tested and demarcated. In order to minish the volume and improve the detection precision,the thick-film mixed technics is used to intergrated the detection circuit and capacitive accelerometer. The circuit is tested and capability is tested,the result shown the test precision is improved one order of magnitude,the linearity and temperature characteristic are improved.更多还原
