巨磁阻 (GMR) 技术
As a world leader in developing, manufacturing, and marketing high-performance integrated circuits, Allegro uses advanced magnetic sensing technology and designs ICs to meet today’s application requirements.
Allegro’s new integrated giant magnetoresistance (GMR) effect technology provides an additional tool in the designer’s toolbox to address new applications and to extend the capabilities of their ICs in existing applications.
GMR offers the ability to improve signal to noise, increase resolution, or reduce the required field level for a given solution (smaller magnets, larger air gaps, etc.). Additionally, sensing in-plane to the wafer or IC surface gives the ability to create new, more robust, differentially magnetic solutions than possible with through-plane sensitive Hall technology.
Allegro is one of very few IC manufacturers who directly integrate GMR technology on top of their semiconductor wafers. This integrated approach offers many advantages, including an improvement in reliability by avoiding additional die-to-die bonding, and allowing for a simpler overall design when integrating current carrying lines or positioning the elements versus an external reference.

巨磁阻 (GMR) 技术
作为开发、制造和营销高性能集成电路的全球佼佼者，Allegro 采用先进的磁性感应技术设计满足当今应用要求的 IC。
Allegro 新推出的集成巨磁阻 (GMR) 效应技术在设计人员的工具箱中增添了一种工具，不仅可以满足新应用的需求，也可以扩展其 IC 在现有应用中的功能。
对于给定的解决方案（磁体较小、气隙较大等），GMR 能够改善信噪比、提高分辨率或降低所需的场强。 此外，晶圆或 IC 表面的平面内感应功能可用于创建新的、更强大的差分磁性解决方案，这是平面直通霍尔感应技术无法实现的。
Allegro 是直接将 GMR 技术集成在半导体晶圆上的为数不多的几家 IC 制造商之一。 这种集成方法具有许多优点，例如，可避免额外的芯片间键合以提高可靠性，以及在集成载流线路时或定位元件时实现比外部基准更简单的整体设计。
