Abstract
A device with position detection includes: a first hall element; a second hall element; a differential amplifier configured to generate a subtraction voltage by differentially amplifying a first hall voltage generated by the first hall element and a second hall voltage generated by the second hall element; a summing amplifier configured to generate a sum voltage by summatively amplifying the first and second hall voltages; a comparer configured to compare a reference voltage with the subtraction voltage to generate an error voltage; and a current converter configured to generate a bias current provided to the first and second hall elements, based on the error voltage, wherein the device is configured to detect a position of a detection object based on the sum voltage.
