Latest Patents

Mather's latest patents include a groundbreaking process for integrating a single chip three-axis magnetic field sensor. This semiconductor process incorporates three bridge circuits, each containing magnetoresistive sensors arranged as a Wheatstone bridge. This design allows for the detection of magnetic fields in three orthogonal directions. The process involves various deposition and etch steps that form the magnetoresistive sensors and a series of flux guides on one of the bridge circuits, enabling the transfer of a 'Z' axis magnetic field onto sensors oriented in the XY plane.

Another significant patent by Mather is the apparatus and method for reset and stabilization control of a magnetic sensor. This invention determines the magnitude and direction of at least one of a reset current and a second stabilization current. These currents produce a reset field and a second stabilization field, respectively. When applied to an array of magnetic sense elements, they minimize the total required stabilization and reset fields during the operation of the magnetic sensor. This innovation ensures that the low field sensor operates optimally, achieving the highest sensitivity and lowest power consumption around a fixed external field operating point.
