Title:
MAGNETIC SENSOR MODULE
Document Type and Number:
WIPO Patent Application WO/2019/139063
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a magnetic sensor module with enhanced accuracy or reliability. This magnetic sensor module (1000) comprises a first magnetoresistive element (12), a second magnetoresistive element, and a detection circuit (10) into which are input the signal output from the first magnetoresistive element and the signal output from the second magnetoresistive element. The first magnetoresistive element (12) comprises a first bridge circuit (WB1) for forming a sine wave signal and a second bridge circuit (WB2) for forming a cosine wave signal. The second magnetoresistive element comprises a third bridge circuit for forming a sine wave signal and a fourth bridge circuit for forming a cosine wave signal. First to eighth magnetoresistive pairs (MRP1-MRP8) are arranged so as to be separated into eight regions (R1 to R8) arrived at by equally dividing the upper surface of a substrate in the circumferential direction.
