Rotation detector for use in motor control and antiblocking brake system of vehicle has second MRE in first MRE circuit and fourth MRE in second MRE circuit symmetrical with regard to central line

摘要

A first magnetic-field dependent resistance element (MRE) (12) in a first MRE circuit (10) and a third MRE (14) in a second MRE circuit (11) are symmetrically arranged with regard to the central line (7) of a bias magnetic field. A second MRE (13) in the first MRE circuit and a fourth MRE (15) in the second MRE circuit are also symmetrically arranged with regard to the central line of the bias magnetic field.
