Giorgio Ferrari received the Master degree and the Ph.D. degree from Politecnico di Milano in Electronics Engineering in 1999 and 2003, respectively. In the 2001 he has carried out part of the research activity in STMicroelectronics (Fremont, USA) on the developing of a high-speed sense amplifier for flash memories. From 2002 to 2003 he held a grant in the MDM Laboratory of Italian Institute for the Physics of Matter (Agrate Brianza, Italy) where he studied theoretical and experimental aspects to detect single electron spin resonance effects on the random telegraph noise of silicon MOSFET devices. In 2005, he joined the Department of Electronics Engineering of Politecnico di Milano as Assistant Professor.
His research interests are in the areas of development of very low noise instrumentation for high sensitivity electrical measurements, and the electrical characterization of materials and nano-bio devices. In these fields, he has designed and operated an innovative spectrum analyzer based on correlation techniques that reaches a sensitivity more than two order of magnitude better than commercially available instruments. The instrument allowed the first experimental evidence that macroscopic resistors may produce shot noise, in contrast to common belief.
He has contributed to implement a new current-sensing atomic force microscope able to perform quantitative impedance and capacitance measurements on nanometric areas. The sub-attoFarad capacitance resolution of the instrument has been used for the first measurement of the dielectric constant of a nanoscaled biomembrane patch.
In the biomedical field, he has contributed to develop a bioelectronic nose based on the impedance measurement of few olfactory receptors in order to mimic the animal nose. To sense the tiny electrical signals available from the olfactory receptors in the physiological medium, he has designed innovative integrated circuits in CMOS technology for the measurement of capacitance variation of few zeptoFarad and track the current on a milliseconds time base with a precision of few femtoAmperes.
He is co-author of more than 35 papers on international journals, of 5 chapter books and has contributed more than 45 papers to conferences. He is co-inventor of four patents and has participated to three projects funded by the European Community, serving as coordinator of one work-package.
