摘要

微型磁通门的功耗是影响其整体性能的关键因素。要降低功耗必须保证器件的薄膜铁芯能够在较小的激励电流下进入饱和状态

为此

可以通过降低铁芯的饱和磁场强度Hs来实现这一目标。设计了一种具有多孔结构薄膜铁芯的微型磁通门

经过有限元仿真分析发现

多孔结构能够降低磁通门铁芯的饱和磁场强度Hs

从而获得较小的饱和激励电流

在保证微型磁通门灵敏度的同时

有效降低器件功耗。

Abstract

Power consumption is a key factor which influences overall performance of micro fluxgate sensors. To reduce power consumption

must assure thin film iron core of the device can reach saturation state under small excitation current

by reducing saturation magnetic intensity Hsof iron core to achieve this aim. Design micro fluxgate with porous film core and it is found through finite element simulation analysis. Porous structure can be effectively used as a method to decrease value of saturation magnetic intensity Hs

so as to obtain low saturation excitation current

assure sensitivity of micro fluxgate sensor and effectively reduce power consumption at the same time.
