This course is taught in English. The aim of the module is to learn to analyze and design circuits that are the base of today's electronic analog and digital systems. Building on the foundations provided by previous courses of electrical engineering, electronic devices and circuits, the operational amplifiers are first introduced and used in linear and nonlinear applications. The second topic covers linear and switching power supplies. Then we study the basic modes of operation of switching transistors and use them to analyze the structure of logic gates. The analysis of data acquisition systems completes the module.

Become familiar with analog electronics and electrical aspects of digital electronics. Design small analog systems from specifications. Design simple power supplies for electronic circuits. Design a digital circuit and the interface between it and a load. Understand the classic data acquisition systems and know how to design then from specifications.

The student must know the theory of electrical networks, their time domain frequency domain analysis, the operation in the linear region of bipolar transistors and MOS, the concept of bias and small signal. He/she also needs to know the basic concepts of signal theory and feedback. As for the experimental exercises, the student should have gained some familiarity in using laboratory equipment (oscilloscope, power supply, signal generator).

The course includes 8 two hours (1,5 CFU) experimental laboratory exercises to be performed at the LED. The labs are organized in groups of three or four students. For each lab group must prepare reports that are evaluated by the instructor and constitute part of final examination mark. 1. Operational amplifier characteristics; 2. Active filter; 3. Instrumentation amplifier; 4. Triangular wave generator; 5. Dissipative voltage regulator; 6. Switching converter; 7. Characteristics of logic gates; 8. D / A converter

ModalitÓ di esame: Prova scritta (in aula); Prova orale obbligatoria; Elaborato grafico prodotto in gruppo;
Exam: Written test; Compulsory oral exam; Group graphic design project;
... The examination consists in a written exercise (time available: 30') which followed by an oral test (two questions). The written exercise is corrected at the beginning of the oral test. No textbooks or notes are allowed during the written exam. The mark obtained in the written exercise and oral test accounts for 80% of the final examination mark. The remaining 20% derives from the average of the evaluations of the reports of experimental exercises. This average is calculated on the best six reports of each student. If the student has made less than six reports, the missing reports are mediated by the value 0 / 30.
Gli studenti e le studentesse con disabilitÓ 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'UnitÓ Special Needs, al fine di permettere al/la docente la declinazione pi¨ idonea in riferimento alla specifica tipologia di esame.

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.
