Abstract: A magnetic field sensor includes a plurality of magnetoresistance elements, each having at least one characteristic selected to provide a respective, different response to an applied magnetic field, wherein each of the plurality of magnetoresistance elements is coupled in parallel. Illustrative characteristics selected to provide the respective responses include dimensions and/or construction parameters such as materials, layer thickness and order, and spatial relationship of the magnetoresistance element to the applied magnetic field. A method includes providing each of a plurality of magnetoresistance elements with at least one characteristic selected to provide a respective, different response to an applied magnetic field, wherein each of the plurality of magnetoresistance elements is coupled in parallel.

Abstract: Methods and apparatus for a first photodetector array die having pixels from a first end to a second end and a second photodetector array die having pixels from a first end to a second end. A readout integrated circuit (ROIC) can be electrically coupled to the first and second photodetector array die. One or more microlenses can steer light onto the photodetector arrays.
