Claim 11:
12. The apparatus of claim 1, wherein the quantizer comprises:
an inverter;
a first capacitor and a second capacitor, a right plate of each of the first capacitor and the second capacitor being coupled with an input of the inverter; and
a switchable feedback path coupled between the input and an output of the inverter; and
wherein the controller is configured to:
during a reset phase:
couple a left plate of each of the first capacitor and the second capacitor with a reset voltage, and
enable the feedback path to couple the input with the output of the inverter; and

during a comparison phase:
couple the left plate of the first capacitor with an output of the charge sensing unit,
couple the left plate of the second capacitor with a reference voltage, and
disable the feedback path.
