October 2021 • Taehyeong Jeon, Proloy T. Das, Mijin Kim, Changyeop Jeon, Byeonghwa Lim, Ivan Soldatov, CheolGi Kim
The resolution of planar-Hall magnetoresistive (PHMR) sensors was investigated in the frequency range from 0.5 Hz to 200 Hz in terms of its sensitivity, average noise level, and detectivity. Analysis of the sensor sensitivity and voltage noise response was performed by varying operational parameters such as sensor geometrical architectures, sensor configurations, sensing currents, and temperature. All the measurements of PHMR sensors were carried out under both constant current (CC) and constant voltage (CV) modes…
