VIBRATION RECTIFICATION ERROR CORRECTION CIRCUIT, PHYSICAL QUANTITY SENSOR MODULE, STRUCTURE MONITORING DEVICE, AND METHOD FOR ADJUSTING CORRECTION VALUE OF VIBRATION RECTIFICATION ERROR CORRECTION CIRCUIT

摘要

To provide a vibration rectification error correction circuit capable of reducing an arithmetic load related to correction of a vibration rectification error.SOLUTION: A vibration rectification error correction circuit comprises a first correction circuit that obtains a digital value based on a signal to be measured output from a sensor element capable of detecting a physical quantity, and corrects a vibration rectification error of the digital value by a correction function based on a product of a value biased by the digital value.SELECTED DRAWING: Figure 7
