Testing of high-resolution/middle-speed A/D converters and modules-problems and ways of solving them

摘要

The paper describes solutions, how to improve a quality of basic testing methods to be able to use them for dynamic testing high-resolution/middle speed AD converters and AD modules. The following methods are mentioned: an application of low-distortion band pass filters, a digital correction of a known distortion of a testing signal, an application of a two-tone or non-deterministic test signal. The method, which combines a filtration of a testing signal and a following digital correction, is described and proposed as the perspective one. The AD transfer standard, which is applied for an evaluation and comparison of testing methods and systems, is also mentioned.
