摘要

Current fluxgate sensor probe SPICE models constructed by using arc tangent transfer function method and the diode model in fluxgate sensor simulation had some disadvantages which were non convergence, low simulation accuracy, discontinuously adjusted core characteristics and the model couldn't simulate the hysteresis characteristic. IO characteristics of Schmitt Trigger was similar to the B-H curve of soft magnetic core in shape, for this reason Schmitt trigger was used to construct fluxgate probe SPICE model. HSPICE was used in simulation. Simulation results shown that this model can simulate the real electrical properties of fluxgate probe accurately. This model can be used for fluxgate sensor interface integrated circuit research and fluxgate sensor application, and provide a reference to judge the performance for fluxgate sensors of which core parameters within a certain range.
