Subject fundamentals
The Electronic Circuit Course introduces students to the basic concepts of analog circuit electronics that will be used in subsequent courses. The Course focuses on circuit models of active devices and their use in elementary circuits. The combination of several fundamental stages leads to the study of more complex feedback loops whose properties are analyzed in the Course. A considerable amount of time is dedicated to introduce the fundamentals of electronic measurements, with both systematic aspects (such as uncertainty issues) and practical aspects of laboratory instrumentation; laboratory experiments are carried out on circuits studied in the course.
Expected learning outcomes
At the end of the course, the student will have a knowledge of the models of active devices, elementary amplifier configurations, and the effect of feedback on the circuits. After this Course, the student will be able to analyze simple discrete transistor amplifier circuits, calculating their operating point, their transfer functions and their impedances, using a wide range of calculation methods, both based on simulations (Spice) and manual calculations.
The student will also be able to use the principal laboratory measure instruments and to evaluate the measurements uncertainties.
In detail, the student will be able to:
- Calculate the polarization conditions of an amplifier with bipolar and mos transistors
- Find the equivalent circuit of the active elements
- Determine the type of feedback and evaluate its effects
- Calculate transfer functions and impedances
- Assess which calculation methods best fit the circuit being analysed
- Know the fundamental aspects of laboratory measurements and the rules for the uncertainty propagation according to the deterministic model
- Predict the uncertainty of an indirect measurement according to the deterministic model
- Know the use of basic laboratory equipment
- Use basic laboratory instrumentation

Assessment and grading criteria
The exam aims to ensure the knowledge of the topics listed in the Program and the ability to apply theory and methods to the solution of exercises. The examination consists of a written part and a subsequent compulsory oral part. The final vote is determined taking into account both written and oral tests.
The 2-hour written test is divided into two parts, one focused on measurements (theory and exercises) and one related to circuit theory (theory and solution of problems). During the test, students are not allowed to consult any teaching material. Both parts must be sufficient to pass the written test.
The oral exam, reserved for students who passed the written test, provides theoretical and practical questions on electronic circuits, laboratory exercises and circuit simulation. Generally, the written and oral parts must be taken in the same exam session.
