System and methodology for analog-to-digital converter linearity testing

摘要

A method for testing an analog-to-digital converter is disclosed. In an implementation, the method may include providing input data to analog-to-digital converter circuitry. The analog-to-digital converter circuitry generates an output code based upon the input data. The method includes generating expected output code based upon the corresponding input data and generating an output code error signal based upon the difference of the output code and the expected output code. A predicted code error signal is modeled based upon corresponding code. The method also includes generating a noise error signal representing a difference between the output code error signal and the predicted code error.
