Description
Energy-efficient comparators are crucial for Analog-to-Digital converters for the Internet of Things. For this reason, a lot of publications are looking at how to improve the energy efficiency of this block and one of the most interesting novelty is the Edge-Pursuit Comparator, published in 2019. This comparator is based on a ring oscillator and exploits two different paths of the signal with two different speed to make the comparator take a decision. The goal of this project is to develop the mathematical framework and analysis of the working principle of a novel comparator utilizing the edge pursuit principle.
This is a mix of theoretical and practical project. It will consist of mathematical analysis and simulations of the comparator and, if the analysis is promising and time permits, implementation and layout. A more detailed project description will be tailored to the type of the project (master or semester).
This project is available for both a semester project or a master thesis.
If the project goes well, there is the chance to publish a scientific paper.
