Giannicola Angotzi

About

I received the laurea degree in electronic engineering at the University of Cagliari, in 2003 and the Ph.D. degree in electronic and computer science in 2007 from the same University. During my PhD I was mainly interested on vision systems to whom is demanded not only to acquire the scene with a given precision and resolution, but also to be capable of extracting and collecting information from the observed scene. In this contest I studied novel full-custom circuit solutions to meet the required design specifications independently from matching impairments of the devices. A vision chip embedding sensing and processing capabilities was successfully conceived, designed and realized. I was also interested on the design of Analog to Digital Converters, and in particular on the impact of matching impairments of passive components on multistep converters.\\
In 2008 I joined as postdoctoral researcher the Robotics Brain and Cognitive Sciences department at the "Istituto Italiano di Tecnologia" and since 2014 I was first researcher-technologist then researcher in the Neuroscience and Brain Technologies department with the group of L. Berdondini. My recent research activity is currently focused on the conception and design of high-density, low-power implantable CMOS neural probes for massively parallel \textit{in vivo} recordings from the central nervous system. Also, I am interested in micro-scale devices that can be embedded into living 3D cell assemblies to provide in-tissue wireless sensing and monitoring of biosignals.\\
I have a strong background on the conception, design, realization and validation of Very Large Scale Integration (VLSI) Circuits.
