Eland, E.N. (author), Karmakar, S. (author), Gonen, B. (author), van Veldhoven, Robert (author), Makinwa, K.A.A. (author)This article describes a discrete-time zoom analog-to-digital converter (ADC) intended for audio applications. It uses a coarse 5-bit SAR ADC in tandem with a fine third-order delta-sigma modulator (ΔΣM) to efficiently obtain a high dynamic range. To minimize its over-sampling ratio (OSR) and, thus, its digital power consumption, the...journal article 2021
