This course gives students an introduction to the basic concepts and techniques of analog electronics. After a review of the models of bipolar and MOS transistors, the course presents their application through a systematic study of elementary single-transistor amplifiers, then extended to the case of multistage systems. The properties and advantages of negative feedback in electronic circuits are examined, and alternative approaches for the analysis of feedback amplifiers are introduced. A part of the program is devoted to the use of basic laboratory instruments. Five lab sessions are organized to make students proficient with modern laboratory instrumentation.

The theory is presented in class mostly at the blackboard, and immediately applied to the study of circuits of increasing complexity. Alternative approaches to the solution of typical numerical problems are presented and discussed. Five laboratory classes are devoted to practicing the use of basic modern instrumentation and to determine experimentally the transfer function of simple multi-stage BJT amplifiers.

Modalità di esame: prova scritta; prova orale obbligatoria;
The exam includes a written test and an oral session. The written test, with an approximate duration of 3h15min, includes: • a 40 min long closed-book section (where the use of textbooks, notes etc. is not allowed) with questions and short numerical problems on electronic measurements; • a 20 min long closed-book section with questions on electronic circuit theory; • an open-book section (2h15min, where students can use textbooks and notes, but no electronic device apart from pocket calculators) with numerical problems on electronic circuits. The texts of all written tests since 2012 and their numerical solutions are available on the course website. The overall score of the written test is a weighted average of the scores of the closed-book (30%) and open-book (70%) sections. The students whose written test score is 18/30 or higher are admitted to the oral exam. The oral exam starts from a review of the written test and includes a mandatory part on electronic circuits (40 min), with at least two questions on the course topics, and an optional part on electronic measurements (15 min) with two questions. The final score is an average of the written and oral scores. The grading is based on the ability of the student to address the analysis of analog circuits, to derive numerically correct results, and to discuss the fundamental concepts presented in the course.
