In this paper, the sensitivity distortion of Hall plate based and split-drain magnetic field effect transistor (SSD-MAGFET) based magnetic sensors under the alternating magnetic field is investigated. Based on the outputs of the both hall plate based and SSD-MAGFET based sensors are sinusoidal functions of displacement of a rotating magnetic field strength, we propose to analyze the sensitivity of the sensors by spectral analysis. The empirical results show that conventional Hall plate based sensor suffers from greater spectral distortion when compared to that of SSD-MAGFET based sensors, which implies SSD-MAGFET based sensors can achieve better accuracy in high speed application without the needs of charge accumulation.
