Claim 10:
11. The apparatus of claim 9, further comprising a second capacitor coupled between the measurement capacitor and the comparator;
wherein the controller is configured to reset both the measurement capacitor and the comparator are reset prior to the first measurement period, the second measurement period, and the third measurement period to store an error signal representing a reset noise of the measurement capacitor and an offset voltage of the comparator; and
wherein the second capacitor is configured to:
provide a first error-compensated version of the first voltage to the comparator to generate the first decision based on combining the first voltage with the error signal;
provide a second error-compensated version of the second voltage to the comparator to generate the second decision based on combining the second voltage with the error signal; and
provide a third error-compensated version of the second voltage to the comparator to generate the third decision based on combining the second voltage with the error signal.
