A Biomedical Imaging System Based on an Integrated Array of Magnetoresistive Sensors

Magnetic tunnel junctions (MTJs) provide a valuable platform for biomedical imaging applications especially if the sensors are built on top of a CMOS integrated circuit. In this paper, we devise a platform for readout of MTJs that rely on analog circuitry with relaxed specifications, while part of the system complexity is leveraged to digital post-processing. The proposed system comprises a high-d...
