Mohammadkarimi, M. (author), Leus, G.J.T. (author), Rajan, R.T. (author)A new method for joint ranging and Phase Offset (PO) estimation of multiple drones/aircrafts is proposed in this paper. The proposed method employs the superimposed uncoordinated Automatic Dependent Surveillance-Broadcast (ADS-B) packets broadcasted by drones/aircrafts for joint range and PO estimation. It jointly estimates range and PO prior...journal article 2024

Mohammad Zaki, A.R. (author), Nihtianova, S. (author)State-of-the-art readout integrated circuits (ROICs) operating in particle-counting mode are gravitating toward high time resolution, low-noise, and low-power analog readout frontends to detect and register the arrival time of charge signals with a high accuracy. To achieve a time resolution of a few nanoseconds, an intermediate stage, known as...conference paper 2023

van Prooijen, Birgit (author)While the Minimum Euclidean Distance detection is known to be optimal for channels affected by Gaussian noise, it has been shown that Minimum Pearson Distance detection (MPD) may perform better when the channel is also affected by an unknown offset, though for a good performance some adaptations for classical binary block codes are necessary. It...bachelor thesis 2022

Zijlstra, Maarten (author)The dolmens erected in the province of Drenthe between 3350-2700 BC are the most ancient monuments of the Netherlands. They consist of a long assemblage of rocks capped with boulders which served as burial chambers for the Funnel Beaker population. Despite their robust look, dolmens are vulnerable. For example, one of the caprocks of dolmen D14...master thesis 2022

Rooijers, C.T. (author), Huijsing, J.H. (author), Makinwa, K.A.A. (author)This article describes an auto-zero stabilized voltage buffer that achieves low offset and low noise with sub-pA input current. A high gain stabilization loop is used to periodically cancel the buffer’s offset. The loop itself is periodically disconnected from the buffer and auto-zeroed, during which its bandwidth is reduced to reduce the...journal article 2022

Schouhamer Immink, Kees A. (author), Weber, J.H. (author)We consider noisy communications and storage systems that are hampered by varying offset of unknown magnitude such as low-frequency signals of unknown amplitude added to the sent signal. We study and analyze a new detection method whose error performance is independent of both unknown base offset and offset's slew rate. The new method...journal article 2022

Yuan, Wucheng (author), Liu, Ke (author), Wang, S. (author), Tan, C. (author), Ye, H. (author)The limitation of Silicon based power MOSFET was broken by the super-junction (SJ) structure, which can provide lower specific on-resistance and higher breakdown voltage compared with the conventional power MOSFET structure. Multi-epitaxial and multi-ion-implant technology, as a mature manufacturing process of the SJ structure, has been widely...conference paper 2022

Bu, R. (author)Data transmission is ubiquitous in all walks of life, ranging from basic home and office appliances like compact disc players and hard disk drives to deep space communication. More often than not, the communication and storage channels are noisy, and data might be distorted during transmission. However, noise is not the only disturbance during...doctoral thesis 2021

Tegtmeier, Kaja (author)Most nations have agreed to limit the emission of greenhouse gases within the Paris Agreement. The agreement relies on the assumption that all participating nations have accurate means of estimating carbon emissions and offsets accurately. However, global carbon emission accounting methodologies lack accuracy in approach and required carbon...master thesis 2021

(author)In this paper, a fully-synthesizable digital-to-time (DTC)-based fractional-N multiplying delay-locked loop,(MDLL) is presented. Noise and linearity of synthesizable DTCs are analyzed, and a two-stage synthesizable DTC is proposed in which a path-selection DTC is used as the coarse stage and a variable-slope DTC is used as the fine stage.

Rooijers, C.T. (author), Karmakar, S. (author), Kusuda, Y. (author), Huijsing, J.H. (author), Makinwa, K.A.A. (author)In chopper amplifiers, the interaction between the input signal and the chopper clock can give rise to intermodulation distortion (IMD). This chopper-induced IMD is mainly due to amplifier delay, which causes large pulses at the output of the amplifier's output chopper. This article proposes the use of a so-called fill-in technique to eliminate...journal article 2021

van Hemert, G. (author)Storage systems, such as Flash memories, suffer, apart from the always present<br/>noise, also from offset. The presence of this noise can decrease the performance<br/>of a decoder using the Euclidean distance significantly. To negate the effects of<br/>offset, a new distance, the modied Euclidean distance, was introduced, which<br/>offers...bachelor thesis 2020

However, when the stored or transmitted signals are also corrupted by an unknown offset, other decoders may perform better. In particular, applying the Euclidean distance on...journal article 2020

Rautmare, Shardul (author)Temperature threshold sensors facilitate temperature protection in microprocessors by indicating when the processor gets overheated or too cold. This thesis presents a BJT based temperature sensor with a programmable temperature threshold from -40°C to 150°C. Comparison of a CTAT voltage with a PTAT voltage gives a one-bit digital output when...master thesis 2019

Osejo Rodriguez, Jorge (author)Over recent years, there has been an increase in demands for rare and precious minerals worldwide. Mostly this is due to the rise of the world’s population and the drive towards a green energy transition and low carbon economy. Prices are rapidly increasing, and there is an identifiable risk of an increasing supply shortage of raw materials,...master thesis 2019

Grappin, Marie (author)Massively reducing Greenhouse Gas (GHG) emissions is one of the biggest challenges of the 21th century. An important deployment of Renewable Energies (RE) can be a key element in attaining this objective. Setting a (high) carbon price would greatly help as it would send a powerful signal to RE investors that it is time to switch from high...master thesis 2019
