Various embodiments relate to classifying comparators based on comparator offsets. A method may include applying, via a strobe, a first voltage to each of a first input and a second input of a comparator to generate a number of output signals from the comparator, wherein each output signal has one of a first polarity and a second polarity. The method may further include in response to each of the number of output signals being the first polarity, applying, via a strobe, an external offset voltage having the second polarity to the comparator to generate a second number of output signals. Further, the method may include in response to each of the second number of output signals being the same polarity, identifying the comparator as a reliable comparator.
