Simulation of output voltage waveform on thin film magnetoresistive sensor

摘要

A novel design model based on slant multi-phase filter (SMPF) theory is presented. The output voltage waveform of magnetoresistive(MR) element is simulated, it is found that the slant angle can affect the output performance of the MR sensor obviously. When the ratio of MR element length to magnetic pole length is five, the decrease of the output is small in the region where the slant angle is from 0 to 5°, less than 20%.
