20150130455 | Magnetoresistive magnetic field gradient sensor - Disclosed is a magnetoresistive magnetic field gradient sensor, comprising a substrate, a magnetoresistive bridge and a permanent magnet respectively disposed on the substrate; the magnetoresistive bridge comprises two or more magnetoresistive arms; each magnetoresistive arm consists of one or more magnetoresistive elements; each magnetoresistive element is provided with a magnetic pinning layer; the magnetic pinning layers of all the magnetoresistive elements have the same magnetic moment direction; the permanent magnet is disposed adjacent to each magnetoresistive arm to provide a bias field, and to zero the offset of the response curve of the magnetoresistive element; the magnetoresistive gradiometer includes wire bonding pads that can be electrically interconnected using wire bonding to an ASIC or to the lead frame of a semiconductor chip package. | 05-14-2015 |
20150091560 | Magnetoresistive sensor for measuring a magnetic field - The present invention relates to a magnetoresistive sensor for measuring a magnetic field. A calculation of the sensitivity to external magnetic fields is provided, and it is shown to be related to the shape anisotropy of the magnetoresistive sensing elements. Moreover, it is shown that sensitivity may be made highest when the shape of the magnetoresistive element is long parallel to the sensing axis, and a magnetic bias field strong enough to saturate the magnetoresistive element's magnetization, H | 04-02-2015 |
