Brief CV

Davide Saguatti was born in Modena, Italy in 1985. He received his B.S. in electrical engineering in 2007 working on digital modeling of acoustic musical instruments, and his M.S. in electrical engineering in 2009 working on numerical simulations of current assisted photonic demodulators, both “somma cum laude” from the University of Modena and Reggio Emilia, Modena, Italy.

Since 2010 he has been pursuing his Ph.D. in Electronics and Telecommunications from the ICT School of the University of Modena and Reggio Emilia, working on numerical simulations and analysis of InP HEMTs, photonics demodulators, light-emitting devices and radiation detectors.

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 has been member of IEEE since 2008.

Research Activity

Scientific activity concerns/has concerned:

1. Physical modeling of acoustic instruments (BS thesis project)
2. Numerical simulations and design of Current Assisted Photonic Demodulators (CAPDs) for a TOF-based 3D CMOS image sensor
3. Numerical simulations, design and characterization of InP-based HEMTs and MOS-HEMTs for high-frequency, high-efficiency RF applications
4. Analysis of efficiency issues on GaN light emitting diodes (LEDs)
5. 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.
