Abstract:The paper analyzes the impact of non-linearity of asynchronous Sigma-Delta analog-to-digital converter (ASD-ADC) characteristics on the quantization process. The ASD-ADC is considered as time-interleaved multi-resolution converter that employs two different characteristics for signal processing alternately. As shown in the paper, the classical uniform quantization of the asynchronous Sigma-Delta modulator (ASDM) output signal by time-to-digital converter is ineffective due to the different shapes of ASDM chara… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
