OVERVIEW

The teaching aims at providing the basic notions of electric circuit theory and to introduce the main semiconductor devices and their application in simple circuits. The main topics are the basic analysis of linear circuits in DC and AC steady state, the description and functioning of diodes, bipolar junction transistors and operational amplifiers and their application in rectifiers and amplifiers.

## AIMS AND CONTENT

LEARNING OUTCOMES

Circuit theory in direct and alternate current, electric characteristics of elementary components, impedances and admittances, diodes, transistors and amplifiers; analysis of simple electric and electronic circuits, measurements of electric quantities. Component dimensioning in an electric or electronic circuit.

AIMS AND LEARNING OUTCOMES

At the end of the teaching, the student will be able to analyze a linear, time-invariant circuit in DC and AC steady state. The student will also be able to analyze simple rectifier circuits based on diodes and simple amplifiers based on bipolar junction transistors and operational amplifiers.

PREREQUISITES

Linear algebra, complex numbers.

Teaching methods

The teaching is divided in theoretical lessons (48 hours) and in four laboratory lessons (12 hours).

SYLLABUS/CONTENT

Basic notions on electromagnetism; limits of validity of lumped circuit theroy; voltage, current, flux, charge and power; Maxwell equations.

Bipoles, N-poles and two-ports; Kirchhoff laws.

Fundamental adinamic bipoles (resistor, ideal generators); connection in series and in parallel; resistive dividers; Thévenin and Norton models; analysis of liner circuits in DC steady state.

## LESSONS

Teaching methods

The teaching is divided in theoretical lessons (48 hours) and in four laboratory lessons (12 hours).

LESSONS START

Regular (see didactic calendar at http://www.ingegneria.unige.it/index.php/orario-e-calendario-delle-lezioni)

## EXAMS

Exam description

The exam consists in an oral discussion divided into three parts:

1. a topic chosen by the student among the ones seen during the teaching (about ten minutes);
2. exercise on the analysis of a linear time-invariant circuit at DC or AC steady state;
3. exercise on the analysis of a circuit containing semiconductor components (diodes, bipolar junction transistors or operational amplifiers).

Assessment methods

The exam allows verifying the ability of the student to summarize exhaustively one of the topics of the teaching and to analyze linear circuits at steady state and simple circuits containing semiconductor devices.
