ARRANGEMENTS FOR SELF-TESTING A CIRCULAR VERTICAL HALL (CVH) SENSING ELEMENT AND/OR FOR SELF-TESTING A MAGNETIC FIELD SENSOR THAT USES A CIRCULAR VERTICAL HALL (CVH) SENSING ELEMENT

摘要

A switching arrangement around a circular vertical Hall (CVH) sensing element can provide a normal mode configuration responsive to magnetic fields at some times, and at least one of a first and a second self-test mode configuration not responsive to a magnetic field but simulating a magnetic field at other times. A corresponding method is also described.
