20401807 - EXPERIMENT IN PHYSICS III

The course deals with the basic concepts and techniques of electronics. The primary objective of the course is to deepen the understanding of the electronic devices that are part of the technologies that surround us and the role they play in the measurements of physical quantities. Particular attention will be paid to increasing knowledge for: identifying the applications and potential of electronics in physics laboratories; recognize the different electronic components used for the different electronic functions; be able to analyze simple analog and digital electronic circuits; be able to manage the basic instrumentation present in an electronics laboratory. To achieve the objectives, the course includes lectures, numerical exercises, use of circuit simulators, laboratory exercises.

Programme

Fundamental concepts of electronics used in the field of measurement of physical quantities. Introduction to semiconductor physics, junction diodes, BJT and MOS transistors. Introduction to the concept of amplification and the principles of feedback. Applications of operational amplifiers. Introduction to digital electronics and applications of logic gates.
The lessons are complemented by numerical and laboratory exercises (the latter with compulsory attendance).
The purpose of the laboratory exercises is to provide students with the necessary knowledge and practical skills, so as to enable them to use the electronic instruments and electronic components studied during the theoretical lessons. Students must carry out laboratory exercises and submit, at the end of the exercise, a report describing the activity carried out, the data collected and the numerical calculations carried out.
List of laboratory exercises: study of the resonance frequency of an RLC filter (introductory experience aimed at becoming familiar with the laboratory instrumentation); applications of operational amplifiers (three experiences); applications of circuits with junction diodes (two experiments); applications of BJT and MOS (two experiences); applications with logic gates (two experiences); use of the Geiger counter.


Core Documentation

To prepare for the exam, in addition to consulting the teaching material provided by the teacher, students can consult the following texts:
(a) G. Schirripa Spanish, Applied Electronics, Efesto Editions, ISBN 978 88 9910 456 6
(b) Thomas C. Hayes and Paul Horowitz, Learning the Art of Electronics: A Hands-On Lab Course, Cambridge University Press (2016) ISBN 978 05 2117 7238


Type of delivery of the course

Lectures carried out with the aid of projection of images and audiovisual materials, numerical exercises with the use of the LTspice simulator, compulsory participation in at least eight laboratory exercises concerning electronic measurement experiments. Each laboratory experience is completed by the student with a report illustrating the procedures followed and the results of the measurements made.

Type of evaluation

Learning is progressively verified throughout the course through laboratory reports and oral interviews organized after two or three laboratory experiences. Furthermore, learning is verified through a further laboratory test (to be faced by students who were insufficient during the ongoing assessments) and by an oral interview. The oral exam is aimed at ascertaining: [1] knowledge of the physics of the experiences performed; [2] mastery of scientific language; [3] theoretical contents of data analysis methods; [4] ability to use, critically and consciously, the tools used in the laboratory.
