Subject fundamentals
The course is taught in English.
This is a mandatory course (can be replaced by "Elettronica Analogica e di Potenza", in Italian) for the Master Degree in Electronics. The course aim is to review and study in depth various subjects of Analog Electronics, with an emphasis on contents related with telecommunication applications. The most relevant issues related with analog and telecommunication subsystems are analyzed in detail, to establish a reference point for the following courses, which addresses more specific subjects.

Delivery modes
Practice classes address limited-complexity designs, related with subject of the previous lectures. The design includes numerical evaluation, which requires hand-held scientific calculators (personal).
Experimental labs are focused towards verification of the circuits designed in the practice classes, with measurements on these same circuits. The course includes a total of 7 or 8 lab sessions. Labs are carried out by teams of 3/4 students, who must prepare a homework before the lab session, and deliver a report on the design lab measurements. The reports are verified, and taken into account for the final mark.
Texts, readings, handouts and other learning resources
A textbook which includes most of the addressed subject is: Design with Operational Amplifiers and Analog Integrated Circuits (III Edition), McGraw-Hill, 2002.
Radio systems and PLLs are described in: D. Del Corso, Elettronica per Telecomunicazioni, McGraw-Hill, 2000 (in Italian, available as print-on-demand in the publisher’s website).
Copies of slides used in the lectures, examples of written tests, instruction manuals for the lab are available from the course website.
Assessment and grading criteria
The final assessment includes a written test and an oral discussion. The written test consists of 2-3 numerical design exercises, related with the main subjects addressed in the course (analog circuits, A/D/A conversion systems and circuits, radio systems and PLLs, power stages). Each exercise may have 4-6 questions; to pass the exam, one must deliver correct answer for at least the first two questions of each problem. The total time for the written test is two hours. The oral discussion lasts about 15’, and concerns all the subjects addressed in the lessons.
The final mark is a weighted average of written test and oral discussion (weight .8) and lab reports evaluation (weight .2). The mark can be improved by developing mini-projects (agreed with the professor), or by preparing good notes from the lectures (to be used in the following years).
