A magnetic sensor package comprising a magnetic multi-turn sensor die and a magnetic single turn sensor die, in which both sensor dies are packaged on the same lead frame. A method of manufacturing the magnetic sensor package is also provided. A magnetic sensor system comprising a rotating magnet and the magnetic sensor package, where the sensor package is arranged so that both sensor dies sit within a homogenous magnetic field, thereby ensuring that the output signal of each sensor is not corrupted by any stray fields.

Magnetic sensor package and magnetic sensing system

Magnetic sensor package

A magnetic angle measurement system having magnetic angle sensors, signal processing circuitry and a processor is disclosed. First signal processing circuitry receives a first subset of outputs of a first plurality of outputs from a first magnetic angle sensor and determines first magnetic angle data based on the received first subset of outputs. Second signal processing circuitry receives a second subset of the outputs from the first magnetic angle sensor and determines second magnetic angle data based on the received second subset of outputs. Third signal processing circuitry receives a second plurality of outputs from the second magnetic sensor and determines third magnetic angle data based on the received second plurality of outputs. The processor compares the magnetic angle data and determines a processing result based on the comparison, where fault tolerance resolution of the magnetic angle measurement system is based at least in part on the processing result.

Apparatus for detecting sensor error

A magnetic device may include a magnetic structure, a device structure, and an associated circuit. The magnetic structure may include a patterned layer of material having a predetermined magnetic property. The patterned layer may be configured to, e.g., provide a magnetic field, sense a magnetic field, channel or concentrate magnetic flux, shield a component from a magnetic field, or provide magnetically actuated motion, etc. The device structure may be another structure of the device that is physically connected to or arranged relative to the magnetic structure to, e.g., structurally support, enable operation of, or otherwise incorporate the magnetic structure into the magnetic device, etc. The associated circuit may be electrically connected to the magnetic structure to receive, provide, condition or process of signals of the magnetic device.

Magnetic device with magnetic structure and micro-fluidic structure

An embodiment of a position sensing system includes a signal generation circuit to generate an excitation signal according to a selected characteristic signal, a drive circuit to drive an excitation source with the excitation signal, an input circuit to receive a sensor output while driving the excitation source, a signal detection circuit to identify a component of the sensor output corresponding to the characteristic signal, and a control circuit to determine the position of the movable object as a function of the identified component of the sensor output. The positioning system may be included an electronic camera, where the movable object may be a lens. The excitation source may be a conductive coil, the excitation a magnetic field, and the sensor a magneto resistive sensor. Alternatively, the excitation source may be an optical excitation source, the excitation an optical excitation, and the sensor an optical sensor.
