The course is taught in English. This is a mandatory course (in some curricula it 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 analysed in detail, to establish a reference point for the following courses, which addresses more specific subjects.

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.

A textbook is in preparation and will be possibly ready for the course start. If not draft versions of the book chapters will be made available. 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 however 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.

Modalità di esame: Prova scritta (in aula); Prova orale obbligatoria; Prova pratica di laboratorio;
Exam: Written test; Compulsory oral exam; Practical lab skills test;
Gli studenti e le studentesse con disabilità o con Disturbi Specifici di Apprendimento (DSA), oltre alla segnalazione tramite procedura informatizzata, sono invitati a comunicare anche direttamente al/la docente titolare dell'insegnamento, con un preavviso non inferiore ad una settimana dall'avvio della sessione d'esame, gli strumenti compensativi concordati con l'Unità Special Needs, al fine di permettere al/la docente la declinazione più idonea in riferimento alla specifica tipologia di esame.
Exam: Written test; Compulsory oral exam; Practical lab skills test;
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,). 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 1,5 hours. The oral discussion lasts around 20-30’, and concerns all the subjects addressed in the lessons plus a short verification of the student capabilities in working in a electronic lab. The final mark is a weighted average of written test and oral discussion plus lab reports evaluation (0-2 points). 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).
In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
