Resistor-Based Digital-to-Analog Converters

Transmit digital-to-analog converters have become an essential building block for state-of-the-art Ethernet infrastructures. They are also one of the most significant sources of power consumption in an Ethernet physical layer (PHY) transceiver. These devices must maintain high linearity and a well-defined impedance of 100 Ω while operating at a...

UVC Seed Sterilization BSc Thesis: Software and Control

In this thesis for the Bachelor’s Degree in Electrical Engineering, a Control Unit (PCB and software) is designed for inside the UVC Seed Disinfection Machine of Team UVO. The machine consists of four modules: the Control Unit, the LED Driver, the motor controller and the power supply. The Control Unit allows a user to input the intensity per...

Reciprocal mixing and inherent nonlinearity in N-path filters

N-path filters promise to miniaturize RF receivers by replacing various fixed off-chip filters with a single programmable on-chip filter. This research investigates some of the issues of receivers with N-path filters under strong blocker conditions: reciprocal mixing and inherent nonlinearity. First, a technique for reciprocal mixing...

Detection System and Enclosure Design: for Quantum Random Number Generation

This report focuses on the design and implementation of both a detection system and an enclosure, which are designed to be used in a quantum random number generator. These parts are designed to be manufactured using off-the-shelf components to make the quantum random number generator affordable and accessible to a completely new user-group that...

Cryogenic SiGe Bipolar Amplifiers for Spin-Qubit DC Readout

In recent years, quantum computers have become increasingly popular, with high-profile companies in-vesting more and more resources into the development of quantum-computing prototypes. Such interest is motivated by the exponential increase in the computing power that quantum computers offer over classical computers, which may be used in several...

Cryogenic DAC for the Biasing of Spin Qubits

Disruptive changes in the fields ofcryptography and quantum chemistry can be achieved through quantum computing,as specific computations can be sped up significantly. Thousands to millions ofqubits are required to perform these computations, illustrating the need forlarge quantum computers. These qubits must be cooled to...

Design of a Wideband Wide-Scan Connected Slot Array Antenna Using Artificial Dielectrics

Low-SNR Operation of FSK Demodulators

This thesis introduces the concept of phase rotation cancellation (PRC) as a previously unknown error mechanism in narrow-band FSK systems, and proposes a new FSK demodulation algorithm to resolve PRC errors. Phase rotation cancellation is defined as an event where the signal phasor rotation in the IQ plane is temporarily cancelled by the...

Cryogenic CMOS supply voltage regulator for quantum computing applications

Quantum computers are able to deal with large problems, like molecular modelling, financial prediction and cryptography. A classical controller is used to control the qubits of the quantum computer. A proposed controller, operating at 4K, needs a clean voltage supply in order to function well. The long interconnects between the room temperature...
