Параметричний синтез точностних характеристик самокаліброваних АЦП

Abstract

The dependence o f the AD conversion error from the self-calibration parameters using weight redundancy, namely division fo r “accurate and “поп-accurate ” bits, base o f the number system and maximum deviation o f the bit weights, is analyzed in the article. The analytical dependences allowing to determine optimal parameters o f self-calibration procedure are derived. Graphical results o f self-calibration and AD conversion modeling are also presented.
