Brief CV

Davide Saguatti was born in Modena, Italy in 1985. He received the B.S. degree (summa cum laude) in Electrical Engineering (working on digital modeling of acoustic musical instruments) and the M.S. degree (summa cum laude) in Electrical Engineering (working on numerical simulation of current-assisted photonic demodulators) from the University of Modena and Reggio Emilia, Italy, in 2007 and 2009, respectively. He is currently working toward the Ph.D. degree in electronics and telecommunications (working on numerical simulations and analysis of inorganic and organic semiconductor devices and sensors) in the International Doctorate School in Information and Communication Technologies, University of Modena and Reggio Emilia, Italy. In 2010 and 2011, for 9 months totally, he joined Prof. M. Missous’ research group within the Microelectronic and Nanostructures Group of the School of EE&E at the University of Manchester, Manchester, UK, as a Honorary Visitor. Davide is co-founder and vicepresident of RSens srl, the first joint spin-off of the University of Modena and Reggio Emilia and the University of Trento, which designs and produces innovative electronic sensors for Radon gas detection. Davide has been member of IEEE since 2008.

Research Activity

Scientific activity concerns/has concerned:

1. Physical modeling of acoustic instruments (BS thesis)
2. Numerical simulations and design of current-assisted photonic demodulators (CAPDs) for a TOF-based 3D CMOS image sensor (MS thesis)
3. Numerical simulations, design and characterization of InP-based HEMTs and MOS-HEMTs for high-frequency, high-efficiency RF applications
4. Numerical simulations and analysis of efficiency issues in GaN light-emitting diodes (LEDs)
5. Numerical simulations and analysis of organic light-emitting transistors (OLETs) and field-effect transistors (OFET) for lighting and sensing applications
6. Design and fabrication of innovative radiation sensors

Current Assisted Photonic Demodulators

Within the project [1], 0.18 um CMOS-based CAPDs has been designed and optimized to be employed as sensors for a TOF 3D imaging system. Thanks to the intrinsic demodulation capability of these detectors, simple sine wave-TOF can be implemented, obtaining information about distance from the phase difference measured between sent and received light beam. With the aid of several numerical simulations, two potential fabrication technologies have been evaluated and the optimal device geometry has been identified, with a deep understanding of the tradeoffs which control DC and AC device behaviours. Noise performance has been measured on the fabricated device, while numerical simulations are going to be carried out to deeply study such aspect.
