Abstract
A magnetic sensor array device is comprised of an array of magnetic sensors arranged on a common semiconductor substrate to measure the multi-axis magnetic field of an arbitrary sized region at high speed with high spatial resolution and high magnetic resolution. This invention further improves a multi-axis magnetic sensor array device fabricated on a common semiconductor substrate with additional optimizations to provide for variable spatial resolution, variable magnetic resolution, and a novel secret key derivation.
