Abstract

I would like to thanks to Professor Wilhelmus Adrianus Maria Van Noije for the opportunity in work as a Ph.D. candidate at the Polytechnic School of the University of São Paulo and by all the challenges imposed to me that have collaborated significantly in the improvements of my professional abilities. I would like to thanks to the Federal University of Pampa for the opportunity of being on leave from the university by 3.5 years that made possible working full time in the Ph.D. studies and to the CNPq research agency for support to this work. I would also like to thanks to professors João A. Martino e Paula G. Der Agopian for all the help in the CMOS transistor characterization, to the IMEC Free-mini@asic and to the MOSIS Educational programs for the free integrated circuit fabrications and to professors João N. Soares Júnior and Márcio C. Schneider for all the suggestions gave me at the qualification exam. I would like to thanks to all the members of the DMPSV department of the LSI at USP, especially to Silvana, for all the conversations at the coffee time and commemoration during my stay in São Paulo. Finally, I thanks to my wife Tanísia for all the help and understanding during this shortage of time phase of my life.
