Sensor unit`s e.g. micromechanical acceleration sensor, offset adjusting device, has matching amplifier and adder for adjusting offset of sensor unit e.g. acceleration sensor, dependent on preset adjusting values

摘要

The device has a matching amplifier (1.7) and an adder (1.81) for adjusting offset of a sensor unit e.g. acceleration sensor (1.1), dependent on preset adjusting values (6). A generator (1.8) and a high pass filter (1.5) are provided for determining the offset of the sensor unit and for generating the preset adjusting values dependent on the determined offset. The matching amplifier is designed for producing an adjusting signal (7) dependent on the preset adjusting values, where the adjusting signal is directly delivered to the sensor unit. An independent claim is also included for a method for adjusting offset of a sensor unit.
