Biografia

I am a PhD student currently working on mostly-digital oversampling Delta-Sigma Digital to Analog Converters (DACs) which are inherently resilient towards analog mismatches. The current target is audio reproduction but the developed architectures can be extended to multiple mixed-signal applications and an Analog to Digital Converter (ADC) can be implemented resorting to the same underlying concepts.
I am working also on other modulation techniques, in particular the DDPM (Dyadic Digital Pulse Modulation) with professor Paolo Crovetti in order to develop other interesting architectures. In the meanwhile I am looking for efficient structures and methods for the interpolation filter usually required for oversampling a low rate signal to cope with the Delta-Sigma paradigm.

I was born in Aosta in 1990, moving to Turin to enroll to the Politecnico, where I got both the Bachelor and the Master degrees in Electronic Engineering. During the Master period I enjoyed the digital hardware design and decided to work on my thesis about an architecture for Depth Image-Based Rendering (DIBR), which is an algorithm used in 3D video compression to recreate virtual points of views for free-viewpoint screens. I found an efficient structure by optimizing it from the algorithm level down to the digital arithmetic blocks. The whole research and development part was very challenging and interesting so I decided to apply for the PhD program under Professor Maurizio Martina after a period of internship on an european project called DISLO-MAN. Initially I was intended to continue the DIBR development for Virtual Reality acceleration but I ended up working on mostly-digital DAC algorithms for audio reproduction as I discovered an interesting architecture while working on it as a personal project in the spare time.
