Abstract
A method of operating an analog to digital converter (ADC) comprises comparing an analog input signal to a reference signal, using a comparator, and generating a comparator output according to the comparison, storing the comparator output in at least one memory unit, monitoring the stored comparator output to determine whether a difference between the analog input signal and the reference signal is within a predetermined range, and detecting a metastability error upon determining that the difference between the analog input signal and the reference signal is within a predetermined range.
