Biography

Antonio Augusto Lisboa de Souza received the B.Sc and M.Sc degrees in Electronics from Federal University of Campina Grande (Brazil) in 1998 and 2001, respectively, and the Ph.D. degree in Electronics from the University of Limoges (France) in 2008. Since 2009 he is with Federal University of Paraiba - Brazil, where he is currently a member of the RFWild laboratory. His research interests concern experimental characterization and compact modeling of microwave active devices, low-frequency noise and RF design.

Abstract

Differently from amplifiers relying only on linear theory for analysis and design, Power Amplifiers (PA) require specific approaches and design tools. Moreover, the active devices in a PA may work close to their physical limits in terms of breakdown voltages, current density and temperature, which must be carefully evaluated. In this introductory seminar, we will mainly explore basic PA concepts such as transistor physical limits, power matching (and its relation to gain matching) and Load-Pull technique. Two PA designs (in different IC technologies) will be briefly discussed.
