Teaching methods
Theory lectures in classroom. Practical exercises on the design of some analog blocks with use of commercial CAD software.
Assessment methods
The final verification is in oral form. The candidate is invited to explain and critically discuss the working principles and the design methodologies of the illustrated analog blocks. The capability of catching motivations, merits and limitations of the different studied solutions is positively evaluated.
Teaching tools
The schemes of some circuit blocks discussed during the lectures are available on the indicated web site.
