PHYSICAL QUANTITY SENSOR AND PHYSICAL QUANTITY DETECTION METHOD

摘要

An object is to realize the configuration in which converting units and the like are assembled among multiple axes in a physical-quantity sensor having a sensor configuration for the multiple axes with high precision or at low cost. In order to achieve this object, the physical-quantity sensor has a following configuration. That is, voltages encoded by mutually orthogonal codes are applied to a plurality of detection elements (5) which respond to different physical quantities, and output voltages from the plurality of detection elements are digitized by a single converting unit (10). Then, in a plurality of decoding units (9), the digitized signals are decoded by the codes corresponding to the respective detection elements.
