Оперативне оцінювання відхилень ваг розрядів АЦП послідовного наближення з ваговою надлишковістю

Abstract

The method of most significant bit’s weight deviation operational assessment for successive approximation ADC that is implemented using weight redundancy. The method is based on analysis of a coding scheme in the main coding process. The method relies on the fact that a set of code combinations of ADC will be limited when applying weight redundancy. A relation between the list of possible code combinations in the output of ADC and the bit deviation was analysed.
