Claim 8:
9. The apparatus of claim 5, further comprising:
a counter configured to output count values based on a periodic clock signal,
a memory configured to store one or more count values output by the counter; and
a comparator configured to:
compare the first voltage against the static threshold voltage to generate a first decision in the first measurement period;
compare the first voltage against the first varying threshold voltage to generate a second decision in the second measurement period;
compare the second voltage against the second varying threshold voltage to generate a third decision in the third measurement period; and

wherein ADC is configured to store a count value representing the first output, the second output, or the third output in the memory based on the first decision, the second decision, and the third decision.
