Abstract:
This article introduces a high-resolution continuous-time delta–sigma modulator (CT DSM) architecture that incorporates a successive approximation register (SAR)-assisted digital noise coupling (DNC) technique and a multi-stage noise-shaping (MASH) structure. The limited maximum stable amplitude (MSA) problem due to the high-order-shaped large quantization error ( $Etextsubscript{1}$ ) in the previous …
