Abstract
This invention describes a real-time failure detection system for the inputs of an analog-to-digital converter. A novel mechanism is proposed that provides recognition of an ADC input pin failure through the digital result obtained. The device includes a specific hardware architecture which can be added to any ADC core. This is especially useful in safety applications (where FMEA is a main concern), as it greatly increases the reliability of the analog data measured.
