Abstract :
The paper presents a new method for the correction of non-linearity errors in ADCs. The method has been designed to allow self calibration in systems where an internal signal can be generated, such as base stations for mobile communications. The method has been implemented and tested in simulation on the behavioral model of a commercial ADCs, and on a hardware setup composed by a data acquisition board and a distorting circuit
