Claim 9:
10. The apparatus of claim 9, wherein the counter is reset at a first start time of the first measurement period, at a second start time of the second measurement period, and at a third start time of the third measurement period;
the ADC is configured to:
based on the first decision indicating that the first voltage becomes equal to the static threshold voltage in the first measurement period, store a first count value from the counter corresponding to a time of the first decision in the memory as the first output;
based on the first decision indicating that the first voltage does not become equal to the static threshold voltage in the first measurement period, and the second decision indicating that the first voltage becomes equal to the first varying threshold voltage in the second measurement period, store a second count value from the counter corresponding to a time of the second decision in the memory as the second output; and
based on the first decision indicating that the first voltage does not become equal to the static threshold voltage in the first measurement period, the second decision indicating that the first voltage does not become equal to the first varying threshold voltage in the second measurement period, and the third decision indicating that the second voltage becomes equal to the second varying threshold voltage in the third measurement period, store a third count value from the counter corresponding to a time of the third decision in the memory as the third output; and

wherein the stored count value is provided as the final output.
