| Zusammenfassung: | The invention discloses a square wave sensor circuit which comprises a Hall element used for outputting a first magnetic field signal and a second magnetic field signal, a first amplifying circuit used for amplifying and filtering the first magnetic field signal and outputting the amplified and filtered first magnetic field signal, and a second amplifying circuit used for amplifying and filtering the second magnetic field signal and outputting the amplified and filtered second magnetic field signal. The first amplifying circuit is used for amplifying and filtering the first magnetic field signal and outputting the first magnetic field signal, the second amplifying circuit is used for amplifying and filtering the second magnetic field signal and outputting the amplified and filtered second magnetic field signal, the reference circuit is used for outputting reference voltage, and the first amplifying circuit is used for comparing the amplified and filtered first magnetic field signal and the second magnetic fie |
