Abstract
A magnetic detection device includes a magnetoimpedance sensor element, a main operational amplifier whose input terminals are connected to a first end and a second end of a detection coil, a first feedback circuit that is connected between an output terminal of the main operational amplifier and the first end of the detection coil and is configured to generate a first feedback voltage, and a second feedback circuit that is connected between the output terminal of the main operational amplifier and the second end of the detection coil and is configured to generate a second feedback voltage with a polarity that inverts a polarity of the first feedback voltage with respect to a predetermined reference voltage as a baseline.
