Abstract: A system may include a first sensor and a second sensor. The second sensor may be configured to receive a trigger associated with synchronizing sampling of a second sensor signal with sampling of a first sensor signal associated with the first sensor. The second sensor may be configured to obtain a second sample associated with a second sensor signal based on the trigger, wherein the second sample is synchronous with a first sample associated with the first sensor signal. The second sensor may be configured to transmit an output signal that includes information associated with the second sample.

Abstract: An integrated circuit (IC) includes an internal clock source configured to generate an internal clock signal; a communication interface configured to receive an external clock signal from an external clock source and a communication frame signal that signals a communication frame during which data communication between the IC and the external clock source is enabled, wherein the external clock signal and the communication frame signal are received in parallel; and a clock monitoring circuit configured to monitor the internal clock signal based on the external clock signal. The clock monitoring circuit is configured to compare the internal clock signal and the external clock signal during the communication frame, and generate a timing error signal if a frequency of the internal clock signal does not satisfy a predetermined threshold relative to a frequency of the external clock signal.

Abstract: A Hall sensor is disclosed. The Hall sensor comprises a first Hall element, configured to detect a component of a magnetic field in a first direction a using a sensitive area of the first Hall element. The Hall sensor further comprises a second Hall element, configured to detect a component of the magnetic field in a second direction b using a sensitive area of the second Hall element. The Hall sensor further comprises a conductor track, configured to generate a calibration magnetic field. The calibration magnetic field has a significant component on the sensitive area of the first Hall element in the second direction b. The calibration magnetic field further has a significant component on the sensitive area of the second Hall element in the first direction a.

Abstract: Methods and apparatuses for comparing redundant signals in functional safe systems are provided, including methods for mitigating differing signal path delays and for signal weighting of the redundant signals are proposed. An Apparatus includes a first signal path for a first measurement signal of a physical quantity, the first signal path having a first signal propagation delay; a second signal path for a second measurement signal of the physical quantity, the second signal path having a second signal propagation delay different from the first signal propagation delay; a delay compensation circuit configured to compensate for a difference between the first and second signal propagation delays to generate delay-compensated first and second measurement signals; and comparison circuitry configured to compare the delay-compensated first and second measurement signals.
