Gonen, B. (author), Karmakar, S. (author), van Veldhoven, Robert (author), Makinwa, K.A.A. (author)This article presents a continuous-Time zoom analog to digital converter (ADC) for audio applications. It employs a high-speed asynchronous SAR ADC that dynamically updates the references of a continuous-Time delta-sigma modulator (CTDSM). Compared to previous switched-capacitor (SC) zoom ADCs, its input impedance is essentially resistive,...journal article 2020
