28724 - Electronics T-2

Learning outcomes

Basic knowledge for the analysis and design of analog electronic circuits.

Course contents

The course is split in two modules, the first of which is shared with the course Circuiti Elettronici Analogici T-A (6 CFU) belonging to the Telecommunications curriculum.

Contents of module I (shared with the course Circuiti Elettronici Analogici T-A)

• Electrical signals and their elaboration through circuits: general concepts, recall of mathematical methods for the analysis of linear time-independent circuits, transfer functions, stability. Linear components (one-port, two-port), network functions.
• Semiconductor junction diode: electrical characteristics, basic compact models, fundamental applications.
• Bipolar junction transistor: electrical characteristics, basic compact models.
• Analysis of some fundamental circuit configurations containing bipolar transistors: current mirrors and current generators.
• Small-signal regime: small-signal equivalent circuits of the electronic devices previously studied.
• Single-stage amplifiers: network functions, biasing problems.
• Multi-stage amplifiers. Differential amplifiers.
• Feedback in electronic circuits. Operational amplifiers and circuits. Applications of operational amplifiers in linear and non-linear circuits.

Contents of module II

• Relaxation oscillators. Design of two-terminal components with negative differential resistance. Astable, monostable, bistable multivibrators. Examples based on operational amplifiers and transistors.
• Sinusoidal oscillators: theory and examples based on operational amplifiers and transistors. Three-points oscillators.

Teaching methods

Class lectures with theory and excercises.

Assessment methods

The final assessment is done through a written test of approximately two hours for Elettronica T-2 and 75 minutes for Circuiti Elettronici Analogici T-A. During the test, the use of cellular phones, books, notes and other written supporting material is NOT allowed. A pocket calculator is necessary for numerical calculations. The test consists in some theoretical questions, concerning the topics developed during the lectures, and one or more exercises aimed at the analysis and sizing of analog circuits of various types similar, but NOT IDENTICAL, to the ones presented in the lectures. The test aims at ascertaining the good knowledge of the concepts and methods developed during the lectures and the ability of applying them to circuits of practical interest. A positive result obtained in a test remains valid until the next test.

Teaching tools

Notes on the first part of the course + texts of past exams with solutions are available on Virtuale.
