Single event effect detection and circumvention in ADCs

A method for detecting a single event effect in an analog-to-digital converter, the method comprising:

• generating, via the analog-to-digital converter, a set of digital signals representative of an analog signal, the set of digital signals being grouped into a frame;
• for each digital signal of the set of digital signals in the frame,
• comparing a magnitude of the digital signal with a threshold;
• and
• outputting an error signal indicating a single-event error of the analog-to-digital converter based at least on the magnitude of the digital signal exceeding the threshold;
• and
• outputting an event signal indicating that an event occurred within the frame based at least on a change of the error signal between adjacent digital signals in the frame.

An electronic device comprising:

• an analog-to-digital converter configured to receive an analog signal and output a set of digital signals representative of the analog signal;
• and
• an event detection engine configured to:
• receive the set of digital signals from the analog-to-digital converter,
• for each digital signal of the set of digital signals, 1) compare a magnitude of the digital signal with a corresponding threshold, and 2) output an error signal indicating a single-event error of the analog-to-digital converter based at least on the magnitude of the digital signal exceeding the corresponding threshold,
• output an event signal indicating that an event occurred within the frame based at least on a change of the error signal between adjacent digital signals in the frame, and
• store event data for the frame in an internal memory of the event detection engine based at least on the event signal indicating that an event occurred within the frame, wherein the event data includes values indicating ceiling errors detected in the frame, values indicating floor errors detected in the frame, and a timestamp at which the event occurs within the frame.
