Kandilakis, E. (author), Serdijn, W.A. (author), Akgün, O.C. (author)In this paper, we present the design of a low-voltage, low-power, and small-area time-mode ADC (TM-ADC) for bio-signal sensing applications. The proposed time-mode ADC (TM-ADC) consists of a programmable oversampling ratio (OSR), voltage-controlled ring oscillator (VCRO) based analog-to-time converter (ATC), followed by an asynchronous unfolded...conference paper 2021

Agarwal, Gayatri (author)MRI machine has evolved tremendously over the years from its inception in order to render high-quality 3D images, best among its companion imaging systems. Of the whole system, RF receiver is the most crucial for its noise performance, which is expected to provide high SNR at all operating conditions. At Philips, MRI’s RF receiver is based on...master thesis 2020

Avdeev, Alexander (author), Dialani, Hitesh (author), Vlaardingerbroek, Daniel (author)The displacement of a loudspeaker cone is not linearly proportional to the voltage/current at its input provided. This is due to electrical and mechanical limitations. The distortion is more noticeable at lower frequencies. This report is one of two reports, that will explain how to minimize this distortion. The motion of the loudspeaker cone...bachelor thesis 2020

Skrekas, Vassilis (author)The field of active implantable medical devices (IMDs) has made huge steps forward in the last years. IMDs are used today for the treatment of previously untreatable conditions as well as the continuous monitoring of the health of patients. The field, where active IMDs have been the most successful, is the field of neurological conditions, on...master thesis 2020

Xerou, Eleftheria (author)This project deals with the past, present, and future theatricality of the Bay of Gibraltar, in relation to the settlements around its edge – Gibraltar, La Linea, Algeciras – and across the strait to Morocco. These landscapes are read as both backdrop and auditorium; the ports are re-contextualised as the wings and aisles, and the Bay is the...master thesis 2020

Xie, S. (author), Theuwissen, A.J.P.A.M. (author)This brief proposes a successive approximation register (SAR) analog-to-digital converter (ADC) whose readout speed is improved by 33%, through applying a digital error correction (DEC) method, compared to an alternative without using the DEC technique. The proposed addition-only DEC alleviates the ADC's incomplete settling errors, hence...journal article 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

Biomimicry design thinking education: a base-line exercise in preconceptions of biological analogiesStevens, L.L. (author), Kopnina, Helen (author), Mulder, K.F. (author), de Vries, M.J. (author)Preliminary empirical research conducted by the leading author has shown that design students using biological analogies, or models across different contexts, often misinterpreted these, intentionally or unintentionally, during design. By copying shape or form without integrating the main function of the mimicked biological model, students...journal article 2020

Chen, Peng (author), Zhang, Feifei (author), Zong, Z. (author), Hu, Suoping (author), Siriburanon, Teerachot (author), Staszewski, R.B. (author)This article proposes a power-efficient highly linear capacitor-array-based digital-to-time converter (DTC) using a charge redistribution constant-slope approach. A fringe-capacitor-based digital-to-analog converter (C-DAC) array is used to regulate the starting supply voltage of the constant discharging slope fed to a fixed-threshold...journal article 2019

Parag, Anirudh Kumar (author)This work focuses on addressing the fundamental limitation on the minimum cold start-up voltage that could be harvested from a thermoelectric element (TEG) for human-body wearable applications. For ultra-low DC voltages, the challenge translates to generating a timed-signal to amplify it up to a value that could be used to drive, say, a boost...master thesis 2019

Admiraal, Arthur (author), Verdoes, Bas (author)Current subsea LiDAR implementations are inherently depth limited, and make LiDAR applications in the deep-sea costly. To this end, the SLiDAR project aims to develop a pressure tolerant LiDAR system for use at any ocean depth. This thesis elaborates the high-level system design of the LiDAR system, as well as the design and implementation of...bachelor thesis 2019

van Wietmarschen, Luc (author)This work proposes a new charge pump design suitable for energy harvesting on small human wearable devices. By using only one system for both cold start and high efficiency harvesting, the required silicon area is heavily reduced. The most fitting energy transducer is determined to be a photovoltaic cell, based on aspects of voltage, power and...master thesis 2019

Peeters, J.W.R. (author), Rohde, M. (author)A new friction-heat transfer analogy for the prediction of heat transfer to turbulent fluids at supercritical pressure is presented. This analogy is based on the observation that the predominent events that determine the turbulent heat flux known as hot ejections and cold sweeps have different thermophysical properties. This observation is...journal article 2019
