Abstract:
Embodiments relate to systems and methods for sensor self-diagnostics using multiple signal paths. In an embodiment, the sensors are magnetic field sensors, and the systems and/or methods are configured to meet or exceed relevant safety or other industry standards, such as SIL standards. For example, a monolithic integrated circuit sensor system implemented on a single semiconductor ship can include a first sensor device having a first signal path for a first sensor signal on a semiconductor chip; and a second sensor device having a second signal path for a second sensor signal on the semiconductor chip, the second signal path distinct from the first signal path, wherein a comparison of the first signal path signal and the second signal path signal provides a sensor system self-test.

Claim (Index 14):
A method of monitoring a monolithic integrated circuit, comprising:\n implementing, on a single semiconductor chip, a main signal path comprising a main sensor; implementing, on the single semiconductor chip, a secondary sensor and a secondary signal path, the secondary signal path separate and distinct from the main signal path and, wherein the secondary sensor comprises at least one characteristic selected from the group of characteristics consisting of:\n fewer second sensing elements than the main sensor comprises first sensing elements, \n the secondary sensor comprises second sensing elements of a smaller second sensitive area than the main sensor comprises first sensing elements of a first sensing area, \n the secondary sensor has a different working principle compared with the main sensor, \n the secondary sensor has different signal encodings compared with the main sensor, \n the secondary sensor has different mapping of sensor signals compared with the main sensor, \n the secondary sensor has different compensation algorithms compared with the main sensor, \n the secondary sensor has a different processing schedule compared with the main sensor, \n the secondary signal path, when compared with the main signal path, has a lower sampling rate, \n the secondary signal path, when compared with the main signal path, has a higher latency time, \n the secondary signal path, when compared with the main signal path, has a lower bandwidth, \n the secondary signal path, when compared with the main signal path, has a smaller analog-to-digital conversion resolution, or \n the secondary signal path, when compared with the main signal path, has a smaller signal range; \n providing the signal of the main signal path as a first output signal and the signal of the secondary signal path as a second output signal; and comparing the first output signal and the second output signal.
