Abstract
Methods and apparatus for a magnetic field sensor IC package having groups of arrays of TMR elements each having a pinning direction. An on-chip coil is routed under the TMR elements to conduct current for generating a magnetic field to stimulate the TMR elements. The device may be configured to sense changes in an applied magnetic field.
Claims22
