The course provides a basic knowledge of the characteristic aspects of electronic systems, presenting the main tools for analyzing their behavior, the implementation choices and the fabrication technologies. In particular, the course addresses the study of some basic modules for Analog Electronics (amplifier stages realized with feedback operational amplifiers and interfacing stages) and introduces the operation principles of semiconductor devices (diodes and transistors). In support to experimental activities, the course provides an introduction to measurement uncertainties and error propagation and to the use of fundamental instrumentation tools in an electronic lab. Finally, the course also includes basic concepts of Electronic Measures, with reference to measurement methods and instrumentation

General organization: 82 hours of Lectures (including numerical exercises and practices) + 18h of experimental labs. Six experimental lab sessions (3 hour each) are proposed to practice with electronic laboratory instrumentation and electrical characterization of pre-assembled analog circuits. The goal of the labs is to test what is presented in the lectures, highlighting the limits of the models. The organization will be such as to favor team working and allow the studets to practice with the preparation of a technical report. Hand calculation exercises will be proposed and solved during classroom lectures.

Modalità di esame: Prova scritta (in aula); Prova orale facoltativa; Elaborato scritto prodotto in gruppo;
The final exam consists of a written test including: 8-12 multiple choice questions (10 points weight); 3-4 numerical exercises (20 points weight) that will be on the main topics of the course (Electronics and Measures) in proportion to number of credits (6 and 4, respectively). During the exam books, notes, slides, and laptop/notebook are not allowed. Students may use a pocket calculator. The time available for the written exam is 2 hours. The examination may be supplemented, at the discretion of the teacher or at the request of students who have at least 24/30 in the written test, by an oral exam on all lecture topics and labs. The final mark is given by the sum of the score of the written exam and the oral evaluation which can provide a score between -10 and +10 points. Students have the option to prepare two lab reports (one related to the electronics lab, one related to the measurement labs) which will be evaluated by the teachers with a score between 0 and 1.5 points each. The evaluation of laboratory reports – if delivered- will be added to the mark obtained by the written and oral exam (i.e. a maximum of 3 points added to the mark obtained by written and oral exam). If the total mark exceeds 32 points, the exam rating will be 30 cum laude.
