摘要
A sensor integrated circuit includes at least two processing channels responsive to the same or different analog input signals to generate respective processed signals. The two processing channels are non-homogenous and, in some embodiments have different processing accuracies. A checker circuit receives the first and second processed signals and is configured to detect a fault in the sensor integrated circuit when the first and second processed signals differ from each other by more than a predetermined amount.
