Sergio Graffi was born on March, 29th, 1938 in Bologna (Italy), where he has always lived in. He accomplished classical studies at "Liceo L. Galvani", then engineering studies at the Engineering Faculty of Bologna University, where he got the laurea degree in Electronic Engineering in 1962. He then joined the Istituto di Elettronica which later merged into the Dipartimento di Elettronica, Informatica e Sistemistica (D.E.I.S.).. He became Assistant Professor in 1963, achieved the Libera Docenza in 1972 and passed an Applied Electronics Full Professor competitive examination in 1976. The main areas of his research activity are: nonlinear oscillators, frequency demodulation, solid-state device numerical analysis and modelling, analog IC macromodeling for the design of low-EMI-susceptibility circuits, cellular neural networks (CNN), analog CMOS IC , chaotic electronic oscillators. He is (co-)author of a few tens of publications.
