Abstract
A method of gain scaling in a charge redistribution analog to digital converter includes the step of segmenting a bit weighted capacitor array into a first segment having at least one capacitor representing a least significant bit and a second segment having at least one capacitor representing a most significant bit. During a sampling phase, an input signal is sampled onto the at least one capacitor of the second segment while the at least one capacitor of the first segment is coupled to a fixed voltage.
