A self-developed magnetic detector is presented, which is made up with 64 Hall sensors assembled as an 8×8 serried array in a 50×50mm quadrate circuit wafer, to catch a weak transient magnetic field. The disadvantage accompanying with compact design is the sharp rise of sensor’s working temperature due to the power consumed is on increasing. An approach in which the 64 Hall elements are connected as a three dimensional magnetic-pixel matrix and are driven by dynamic power is presented. The homologous hardware correction illustrative diagram ...
