  • Silicon integrated accelerometer
    Patent number: 6683358
    Abstract: In an accelerometer, the stress is detected through electric amplification with the use of detecting elements 411-434 having an amplification function arranged on beams 3 and, with the use of a differential amplifier circuits 510 formed on the support base 1, an acceleration component in a detection axis direction to which the stress is applied is outputted as the differential mode and acceleration components in the other axis directions are outputted as the common mode, so that each axis sensitivity ratio between the detection axis sensitivity and the other axis sensitivities is enhanced largely.
