(author)This paper presents a continuous-Time zoom ADC for audio applications. It combines a 4-bit noise-shaping coarse SAR ADC and a fine delta-sigma modulator with a tail-resistor linearized OTA for improved linearity, energy efficiency, and handling of out-of-band interferers compared to previous designs. In 160 nm CMOS, the prototype chip...conference paper 2022

aan het Rot, H.N. (author), Kortmann, L.J. (author), Verbraeck, A. (author), de Vries, G. (author), Kooreman, M. (author), de Bruin, B.J.E. (author)Tabletop games that require the aid of a human facilitator are typically designed for a physical environment. However, during the COVID-19 pandemic, lockdown measures prevented people from gathering. Therefore, tabletop games were sometimes played and facilitated in a mediated environment using online communication tools instead. But this...conference paper 2022

Mehrotra, Shubham (author)Analog-to-Digital Converters (ADCs) used in high fidelity audio applications require high linearity and a wide dynamic range (>100 dB). Moreover, for use in portable electronic devices such as smartphones, tablets, and hearing aids, these ADCs must also achieve high energy efficiency. This requirement of high linearity and high energy...master thesis 2021

Gonen, B. (author)Analog-to-digital converters (ADCs) are an indispensable part of the digital age we are living in, as they form the interface between physical reality and virtual reality. Higher ADC energy efficiency is the dominant focus of ADC design research due to the high impact of ADC energy consumption to total energy consumption of the systems they are...doctoral thesis 2021

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

Liu, Angqi (author)The ΔΣ analog-to-digital converter (ADC) is widely used in audio applications for its high resolution. However, it is less energy efficient compared to Nyquist Rate ADCs. The growing demand for portable and wearable devices poses a more stringent power-efficient requirement on the audio system, and the traditional ADCs architecture is hard to...master thesis 2020

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

Dimopoulos, Giorgos (author)During the last three decades, the Earth’s climate is changing rapidly, with higher average temperatures every year that leads not only to the melting of the ice sheet in the arctic and on most of the glaciers all over the world but also to extreme weather phenomena. The rise of the temperature can affect the Sea Surface Height (SSH) in more...master thesis 2019

Gonen, B. (author), Sebastiano, F. (author), Quan, Rui (author), van Veldhoven, Robert (author), Makinwa, K.A.A. (author)This paper presents the first dynamic zoom ADC. Intended for audio applications, it achieves 109-dB DR, 106-dB signal-to-noise ratio, and 103-dB SNDR in a 20-kHz bandwidth, while dissipating only 1.12 mW. This translates into the state-of-the-art energy efficiency as expressed by a Schreier FoM of 181.5 dB. It also achieves the state-of-the...journal article 2017

Gejadze, I.Y. (author), Monnier, J. (author)In the context of river hydraulics, we develop the idea of a richer local zoom model superposed to a given global model. The local zoom model (2D shallow water equations in flooded parts) describes additional physical phenomena which are not represented by the basic global model (1D shallow-water equations with storage area). The weak coupling...conference paper 2006
