The aim of the module is to teach to analyse and design basic electrical and electronic circuits that are the base of complex embedded analog and digital systems used in mechatronics applications. The module will start from basic building blocks in the DC and AC domains together with the necessary analysis and simulation techniques. A complete section of the module will be used to analyze available technologies and components. The last section is devoted to digital basic building blocks.

Become familiar with passive circuits in DC and AC domain. Become familiar with analog and digital electronics. Design small analog systems from specifications. Design a digital circuit and the interface between it and a load. Become familiar with the experimental lab, instruments and measurement techniques for analog and digital circuits.

Physics: power and energy, basic electromagnetics. Mathematics: algebra of complex numbers, linear algebra and matrix analysis, algebraic linear systems, first-order linear differential equations, basis of Laplace transform.

Part I DC Circuits (2 CFU) • Quantities and Units • Voltage, Current, and Resistance • Ohm’s Law, Energy and Power • Series Circuits • Parallel Circuits • Series-Parallel Circuits Part II AC Circuits (2CFU) • Introduction to Alternating Current and Voltage • Capacitors, Inductors • Laplace transform, Bode diagrams • RC and RLC Circuits and Resonance • Time Response of Reactive Circuits • Transformers Part III Devices (2,5 CFU) • Semiconductors • Diodes and Applications • Transistors (BJT, JFET, MOS) and Applications • The Operational Amplifier • Basic Op-Amp Circuits • I order active filters Part IV Digital Electronics (1,5 CFU) • bipolar and MOS transistors in switching mode, switches, CMOS gates • Static and dynamic parameters, open drain and tri-state output • AND-OR-NOT gates • basic sequential circuits (latches, flip-flops, counters)

The course includes 8 experimental laboratory exercises (4 CFU) to be performed at the LED laboratories. The labs are organized in groups of 3/4 students. For each lab, groups must prepare reports that are evaluated and constitute part of the final examination mark.

Modalità di esame: Prova scritta (in aula); Prova orale facoltativa; Elaborato scritto prodotto in gruppo; Progetto di gruppo;

Exam: Written test; Optional oral exam; Group essay; Group project;

... The final exam consists of two distinct written parts that are carried out together in the same day: one part related with exercises / project analysis (such as those seen during the course and in the laboratory exercises) and a second part related with theory (three or four open questions, 5 minutes time for each question). The first part has a typical duration of about 60 minutes, while the second depends on the number of questions. The exam lasts less than two hours. During the first part (exercises), you can use notes, forms, educational materials, etc... but is NOT allowed the use of personal computers (only classic calculators). During the second part (theory), you cannot refer to anything and you do not need calculators. The two parts are evaluated separately and an average is made: to be considered valid, both scores must be at least greater than 14 /30. The score so obtained is summed with the evaluation of laboratory exercises (delta max. between -2 and +4). The resulting score can be registered as it is or further integrated (in positive or negative) with a possible optional oral session.

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.
