User-friendly software tool for advanced ADC testing

Tamás Virosztek, István Kollár

Abstract

This paper describes a freely available, open source, user-friendly data evaluation program developed for ADC testing with a sine wave. This tool performs multiple kinds of mathematical methods (nonlinear least squares and maximum likelihood) to extract the information from the recorded data. It has been created in the form of a Matlab toolbox for users who have some knowledge in ADC testing, and would like to perform the mathematical computations in an efficient way – especially those that require complex numerical methods <b>Error! Reference source not found.</b>. As it is equipped with a graphical user interface, its usage does not require any programming knowledge, nevertheless one can even get familiar with the framework of the software, as the program files contain the source code that runs using the Matlab interpreter. A further important goal of this software is to create the possibility of publishing reproducible ADC test evaluation results. Statements of related papers can be verified easily: if the raw data are shared, the computations can be repeatedly executed using this software tool.
