发明名称 SENSING METHODS AND SYSTEMS FOR HALL AND/OR MR SENSORS
摘要 Magnetic sensing methods and systems are disclosed. A minimum magnetic signal output and a maximum magnetic signal output can be detected utilizing a sensor comprising a peak detector circuit associated with a filter averaging circuit and one or more magnetic elements (e.g., a Hall element and/or magnetoresistive bridge). An average magnetic signal output can then be determined utilizing the filter averaging circuit when a target begins to rotate in front of the sensor.
