| Abstract: | With the demand of micro satellite to obtain attitude angle using magnetic field vector and realize the micromation of the magnetometer, this paper designs and makes a weak magnetic signal processing integrated circuit. Based on the analysis of the compose of micro magnetometer, a design of the weak magnetic signal integrated circuit was proposed; considering the character of the space, the SOI CMOS technology was adopted to fabricate the circuit. The experiments result show that using the IC, the micro magnetometer not only realizes the micromation and integration, but also has the high performance of detecting the weak magnetic signals |
