Abstract
Provided is a magnetic sensor device capable of suppressing a variation in determination for detection or canceling of a magnetic field intensity, which is caused by noise generated from respective constituent elements included in the magnetic sensor device and external noise, to thereby achieve high-precision magnetic reading. The magnetic sensor device includes: a first D-type flip-flop and a second D-type flip-flop each having an input terminal connected to an output terminal of a comparator; an XOR circuit having a first input terminal and a second input terminal which are connected to an output terminal of the first D-type flip-flop and an output terminal of the second D-type flip-flop, respectively; a selector circuit; and a third D-type flip-flop having an input terminal connected to an output terminal of the selector circuit. The selector circuit includes: a first input terminal (A) and a second input terminal (B) which are connected to the output terminal of the second D-type flip-flop and an output terminal of the third D-type flip-flop, respectively; and a select terminal connected to an output terminal of the XOR circuit. The selector circuit selectively outputs input s…
