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
The course includes a number of two hours experimental laboratory exercises to be performed at the LED. Attendance to the laboratories is not compulsory and will be organized on a voluntary basis for students which want to perform experimental work . However the topics related to the laboratories will be part of the exam and material describing them will be provided to students who will not attend in person. At the beginning of the course a call for participation will be made, according to the coronavirus rules valid at that moment and a schedule of participation will be prepared. The subjects of the laboratories will be a subset of the following list: 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 converters
Several lecture notes in Italian covering almost the entire contents of the module are available on the official Politecnico website, where it is also possible to download the specs of the experimental exercises. For further details and discussions the recommended text is: Sedra / Smith, "Microelectronic Circuits", 5th ed. Oxford University Press. ISBN 0-19-514252-7

ModalitÓ di esame: Prova orale obbligatoria;
The exam is targeted both to evaluate the theoretical knowledge of the sunject and the capability to apply that knowledge to the solution of practical problems. Therefore the examination consists in an oral test (three questions which may be theoretical ones or solution of simple exercises) and the final marking is the sum of the score obtained in each question No textbooks or notes are allowed during the written exam. A computer with a webcam, loadspeakers and a good internet connection are required. The student must be visible during the whole duration of the exam.
