摘要： Method and apparatus for trimming a magnetic field sensor having a first magnetic field sensing element. In embodiments, trimming includes the use of a curve for normalized sensitivity of the first magnetic field sensing element derived from a first curve corresponding to current through a coil in a first direction at a first time to produce a field affecting the first magnetic field sensing element versus an external field and a second curve corresponding to current through the coil in a second direction opposite to the first direction at a second time to produce a field affecting the first magnetic field sensing element versus an external field.

摘要： A sensor package includes a magnetic field sensor and a corruption detection and reset subsystem. The magnetic field sensor has a magnetic sense element and a ferromagnetic structure characterized by a baseline magnetic state. The subsystem includes a detector element, a processor, and current carrying structure positioned in proximity to the ferromagnetic structure. Methodology performed by the subsystem entails detecting at the detector element an altered magnetic state of the ferromagnetic structure, where the altered magnetic state differs from the baseline magnetic state. Methodology further entails determining, at the processor, when a reset action is needed in response to the altered magnetic state and applying a reset magnetic field to the ferromagnetic structure to reset the ferromagnetic structure from the altered magnetic state to the baseline magnetic state.

摘要： The present invention discloses a magnetic field sensing device that utilizes a single coil for calibrating the response of the sensor to compensate for temperature dependent sensitivity drift and also for resetting the magnetic field sensor in order to eliminate hysteresis. The single coil configuration is advantageous since it reduces the size of the sensor chip by decreasing the number of contact pads on the chip and also because it wastes less space, which permits an increase in the density of the magnetoresistive elements on the sensor chip.

摘要： In an embodiment, a circuit is configured to produce a magnetic field signal having a frequency spectrum. The circuit may also produce a temperature signal. A modulation circuit may modulate the temperature signal with a frequency outside the frequency spectrum of the magnetic field signal. The modulated signal and the magnetic field signal may be combined to produce a combined signal. A separation circuit may be configured to separate component signals from the combined signal. The separation circuit may include a first filter, which, when applied to the combined signal, produces a filtered signal; a modulation circuit configured to shift the data representing the temperature signal to a baseband frequency; and a second filter configured to separate the data representing the temperature signal from the combined signal.
