ABSTRACT:
An integrated circuit for analog to digital conversion using a plurality of unit capacitors (201). The value of each unit capacitor (201) has a nonlinear spatial component determined by the location of the unit capacitor (201) on the integrated circuit. A plurality of array capacitors (101a-101e) are formed from the unit capacitors (201) such that each array capacitor (101a-101e) includes a selected group of unit capacitors (201). The unit capacitors (201) that make up each array capacitor (101a-101e) are selected based upon the nonlinear spatial component in the unit capacitance value.
