This course is focused on the main analog linear and non-linear applications of junction diodes, field effect transistors and operational amplifiers. Moreover, it offers a basic knowledge of MOS logical families and digital circuits. The final goal of the course is to teach the students how to analyze and perform measurements on analog circuits, and the design of simple circuits with op-amps and discrete MOS devices.
Course Prerequisites
Basic mathematical methods and on theory of passive linear networks. Principles of electrical engineering.
Teaching Methods
The course includes classroom lessons where the theory of active elements and electronic circuits of the course is developed; classroom exercises where numerical examples are performed on analysis and synthesis of amplifiers and signal processing circuits with discrete elements and operational amplifiers; finally, laboratory activity consisting in measurements on active and passive, linear and nonlinear electronic circuits, selected from those presented during lessons.
Assessment Methods
The exam for the course/Module 'Elettronica' consists of a 2-hour written test with circuits using discrete active elements and operational amplifiers, to evaluate the candidate's ability to apply the analysis methodologies presented during the course. Books and notes are allowed, as well as calculators. Computers are not. The maximum score of the written test 24/30, and can be increased by giving an oral test to evaluate the knowledge of the main analog and digital circuits presented in this course. The oral test is compulsory to fix an insufficient mark of the written test. For students giving also the module Conversione statica dell’energia, the final mark of the full course Elettronica per Ingegneria Industriale is the mean of the marks of the two modules. The final score is out of thirty.
