Course Unit Page

Academic Year 2018/2019

Learning outcomes

At the end of the course the student acquires the 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 73092 Circuiti Elettronici Analogici T-A (6 CFU) belonging to the Telecommunications curriculum.

Contents of module I (shared with the course 73092 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 two hours duration. During the test the use of books, notes and pocket calculators is allowed. The test aims at ascertaining the acquired capability of applying the studied concepts and methods to the analysis and design of analog circuits of various types, similar but not identical to the ones presented in the course. A positive result obtained in a test remains valid until the next test.
