ABSTRACT:
A method for analog-to-digital conversion is provided using successive approximation and a plurality of capacitors including a first set of capacitors and a second set of capacitors, a first side of each of the plurality of capacitors being coupled to a common node. The method includes sampling an input voltage on the first set of capacitors, after the step of sampling leaving a side of at least one capacitor of the first set of capacitors floating, coupling a capacitor of the first set of capacitors, which is not floating, with a capacitor of the second set of capacitors so as to redistribute the charge on the coupled capacitors, comparing the voltage on the common node with a comparator reference voltage level to receive a comparison result to be used for a bit decision, and switching the floating side of the floating capacitor of the first set of capacitors to either a first reference voltage or a second reference voltage in accordance with the bit decision.
