En este Trabajo de Fin de Máster se ha diseñado un sensor asíncrono con una arquitectura del tipo Time-to-First-Spike (TFS), cuyos píxeles son capaces tanto de absorber energía como de sensar iluminación siendo alimentados a los niveles de tensión generados por una unión PN iluminada (entre 250 mV y 500 mV), funcionando de manera autosuficiente...

En este proyecto se realizará el diseño, montaje y la puesta en marcha de un equipo capaz de distribuir de manera eficaz la potencia eléctrica, aplicable a un entorno real como puede ser el vehículo eléctrico (EV) o las microrredes. Este equipo consistirá en tres convertidores DC/DC en paralelo con tres entradas independientes. Se pondrá en...

This Thesis focuses on conceiving, developing, and implementing a novel vision sensor where Single- Photon Avalanche Diodes (SPADs) and event-driven architecture converge in a scalable architecture. The departure from conventional frame-based architectures represents a paradigm shift in SPAD-based sensors, aiming to alleviate the prevalent...

This article presents a self-powered image sensor with a novel pixel architecture with energy harvesting capabilities. Pixels are autonomous entities that can harvest or sense illumination independently. Pixels have a fully asynchronous operation and do not require to be scanned to read out their asynchronous output. The sensor was manufactured...

The demand for sun sensors has skyrocketed in the last years due to the huge expected deployment of satellites associated with the New Space concept. Sun sensors compute the position of the sun relative to the observer and play a crucial role in navigation systems. However, the sensor itself and the associated electronics must be able to...

An essential application of electron microscopy is to provide feedback to tune the fabrication of nanoparticles (NPs). Real samples tend to follow a size distribution commonly linked to the synthesis process used and in turn to their functional properties. This study presents an algorithm for measuring particle size distributions in electron...

PV systems efficiency highly depends on the MPPT strategy to be implemented in the PV converter. Many MPPT methods on the literature are focused on improving the steady state and transient system performance extracting the maximum energy from the sun. In this paper, the impact of the MPPT methods in the PV converter is analyzed focusing the...
