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 measurement setup for a similar comparator that we have designed, measure the performance, and to develop the mathematical framework and analysis of the working principle of this comparator. This project is available for both a semester project or a master thesis. This is mostly an experimental project. It will consist of electrical testing of the chip, simulations and analysis. A more detailed project description will be provided tailored to the type of the project (master or semester).
If the project goes well, there is the chance to publish a scientific paper.
