Title: Magnetic sensor
Inventor: HAYASHI TATSUYA
IPC: G01R33/09
Filed: 2018-07-24
Abstract: To suppress decrease in detection sensitivity due to disturbance magnetic field without adding another magnetic sensor for detecting a disturbance magnetic field.SOLUTION: A magnetic sensor comprises: magnetoresistive elements MR1, MR2 to which detection target magnetic field is applied with phases opposite to each other; an amplifier circuit A1 detecting a difference between ohmic values of the magnetoresistive elements MR1, MR2; and a magnetic bias circuit 30 applying a bias magnetic field with the same phase as the magnetoresistive elements MR1, MR2 based on the sum of the ohmic values of the magnetoresistive elements MR1, MR2. When a disturbance magnetic field, such as earth magnetism, is applied to the magnetoresistive elements MR1, MR2 in the same phase, the sum of ohmic values of the magnetoresistive elements MR1, MR2 changes. According to the invention, based on the sum of ohmic values of the magnetoresistive elements MR1, MR2, the bias magnetic field is applied to the magnetoresistive elements MR1, MR2 in the same phase. This eliminates the addition of another magnetic sensor for detecting disturbance magnetic field, and prevents decrease in detection sensitivity due to the disturbance magnetic field.SELECTED DRAWING: Figure 4
