This thesis describes the design of a low-cost class-S power quality analyzer based on a Raspberry Pi 4. Capable of detecting power frequency, magnitude, voltage dips and swells, harmonics, and total harmonic distortion, the project consists of four main components: the communication protocol, the interface, the algorithms for power quality...

This thesis describes the design of a 3rd order 1-bit delta-sigma modulator whose input-signal range (0 to 1.95V) exceeds its supply voltage (1.2V). By using a passive input stage and a single-OTA resonator, this beyond-the-rails modulator realizes a 3rd order loop filter with only two amplifiers instead of the usual three and thus achieves...

Bidirectional neural recording ICs faces the challenge of simultaneous stimulation and recording. The recording IC should endure large stimulation artifacts while capturing weak neural signals excited by the stimuli. The stimulation artifacts can be as large as hundreds of millivolts, which can saturate the recording front end. Conventional...

Quantum computers exploit the quantum behavior of quantum bits (qubits) that are typically operated at cryogenic temperature. Qubits require an electronic control interface. Nowadays, such classical electronic controllers use bulky instruments operated far fromthe qubits outside the cryostat. To run practical quantum algorithms, thousands to...

Biosignals such as electoencephalogram (EEG), electrocorticogram (ECoG), atrial electrogram (AEG) etc. are being recorded from multiple channels simultaneously to improve the spatial resolution of the signals. Conventional multichannel synchronous Analog-to-Digital Converters (ADCs) are used to convert the analog continuous time signals into...

This thesis describes the design of an ultra-low power temperature to digital converter. It is intended to monitor the excess heat produced during the wireless charging of implantable medical devices such as pacemakers. The TDC is designed to achieve an accuracy of ±0.1 °C (3 sigma) from 27 °C to 47 °C, and ±0.3 °C (3 sigma) from -40 °C to 85 °C...

Analog-to-digital converters are important blocks in any electronic system which act as a bridge between analog signals and digital processors. The conventional SAR ADC employs a binary search algorithm and has emerged as the most suitable solution for low-power applications, due to its excellent power efficiency. The proposed ADC architecture...

Clean drinking water is still not widely available around the globe and therefore remains an unsolved issue. In fact, 1 in 9 people lack daily access to safe water and sanitation. Groundwater is a water supply source that needs minor treatment and thereby presents itself as a good solution to this global issue. Especially in development...

Vette, Marek (author)
This thesis is part of the development of a sensor system for measuring currents in the Nuna solar car. A big problem within this system is the processing of incoming sensor data. Therefore, a solution in the form of a sensor-data-processing-unit was proposed, with its primary focus on the analog-to-digital conversion. The converter should not...

Ursulean, M. (author)
The thesis analyzes the design challenges that arise when developing high-speed ADCs and shows, through an extensive architecture study, that the SAR topology can be used with a sampling rate of 2.5GS/s if asynchronous processing and a multi-bit per cycle approach are adopted. The transistor-level implementation and simulation of a 6-bit SAR ADC...

In this work a 9-bit, 33MHz hybrid SAR single-slope ADC for element-level digitization in 2D ultrasound transducer arrays is presented. This hybrid architecture consists of a 5-bit SAR ADC followed by a 4-bit single-slope ADC. In the comparator design, the dynamic comparator and the continuous-time comparator for the SAR and single-slope...

This thesis describes the design and measurement of an IC which can digitize both capacitance and temperature. Capacitance sensing functionality is added to an existing Temperature to Digital Converter (TDC) without adding significant die area. Two kinds of baseline capacitance compensation techniques have been investigated and their performance...

Analog interfacing is the only way to communicate with a quantum processor, whether it is applying qubit operations or reading their quantum states. There exist other applications where analog interfacing is abundant, e.g. sensor networks, automotive, industrial control, etc. In those applications the use of FPGAs is continuously growing,...

Elumalai, I. (author)
Voltage reference buffers have always been the most power-hungry blocks in switched-capacitor SAR ADCs. High frequency dynamic loading of the buffer by the capacitive DAC causes glitches on the reference voltage, and the buffer has to be fast enough to recover such transients to 1/2 LSB precision in every bit cycle. Such stringent requirements...

In this work a low power SAR ADC with 8.9 ENOB for wireless communication systems is presented. A capacitive charge redistribution DAC with a unit capacitor of 0.5fF is used. The implemented charge-sharing technique, allows the use of 2^(N-1) + 1 unit capacitors, instead of the conventional 2^N , thus decreasing the DAC area and the DAC...

Cardiovascular diseases are leading cause of deaths worldwide. With increasing graying population and limited health infrastructure there is a need for portable and implantable ECG devices to diagnose these diseases early on. In general an ECG device requires three or more electrodes, which need to be applied to the body via a gel, to obtain a...
