ELECTRONIC CIRCUITS AND MEASUREMENTS

This course is one of the compulsory educational activities of the Degree Course in Physical Engineering. It provides the knowledge to understand and analyze the static and dynamic behaviour of RLC circuits , the physics and the operation of the main solid-state electronic devices (mainly diodes and MOSFETs) and their use for the realization of analog and digital electronic circuits and components (amplifiers, logic gates, memories, etc.). The first part of the course deals with the understanding and analysis of linear circuits (linear circuits, frequency analysis, Bode diagram) and with the concepts of semiconductor physics of diodes and transistors and their modeling. The student will be provided with the tools to analyze the main characteristics of some fundamental circuit architectures, such as gain, transfer function, stability and frequency band. The class lectures are complemented by laboratory activities during which the students will be able to simulate and experimentally measure the main parameters of elementary circuits using the appropriate instrumentation.

At the end of the course the student will have learned to solve simple electrical circuits both in time and in frequency through the nodal analysis and the use of the main network theorems. Furthermore he will have learned the basics of semiconductor physics and the functioning of silicon devices such as the pn junction and the MOSFET transistor both in static and dynamic functioning.

Advanced knowledge of mathematics (Analysis 1 and Analysis 2), and the course of Fundamentals of Telecommunications and Mathematical Methods for Physics and Engineering.

The achievement of the teaching objectives is assessed through participation in the activities and exercises assigned during the course and a final written exam. The final written exam consists of problems similar to those carried out in class during group work. The use of notes, books and other teaching material is not allowed during the assignment. A facsimile of the assignment will be made available. In addition tot he written exam an oral exam will be also possible.
