Abstract
An analog to digital converter is provided comprising an array of capacitors for sampling an input, each capacitor having at least one associated switch for controllably connecting a terminal of the capacitor to a first reference voltage or to a second reference voltage; and a sequence generator for generating a sequence of bits, wherein during sampling of the input onto the array of capacitors an output of the sequence generator is supplied to the switches of a first group of capacitors to control whether a given capacitor within the first group is connected by its associated switch to the first reference voltage or to the second reference voltage.
