Course detail

Modeling and simulation of electronic circuits

FEKT-BPC-ESIAcad. year: 2021/2022

Students become familiar with basic principles of computer-aided design of electronic circuits. They will learn the use of Spice-class simulators for circuit analysis and characterization in DC, AC, and time domains; analysis of influence of device parameter tolerances on circuit behavior; stability analysis; and optimization. Further, models of passive and active circuit elements and blocks, creation of new model and part libraries are explained. The methods and procedures are demonstrated on computer-aided design of elementary electronic circuits with operating amplifiers and transistors (amplifiers, oscillators, filters). In frame of an individual project, students will design and characterize a given electronic circuit.

Learning outcomes of the course unit

The graduate is able to (1) apply basic methods for analysis of electronic circuits in the DC, AC, and time domains; (2) use advanced methods for tolerance design; (3) perform optimization; (4) use symbolic analysis including automated simplification; (5) perform thermal analysis, (6) create simulation model for an elemental part or a complex subsystem, (7) completely design a simple electronic circuit and perform its characterization.

Prerequisites

Fundamentals of electronic devices (passive and semiconductor devices) and electronic circuits (basic laws, elemental circuits) are the pre-requisites. Generally, the knowledge of the Bachelor's degree level is required.

Co-requisites

Not applicable.

Planned learning activities and teaching methods

Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations. The methods include lectures and computer laboratories. Course is taking advantage of e-learning (Moodle) system. Students have to do a single project/assignment during the course.

Assesment methods and criteria linked to learning outcomes

Students can obtain 40 points for the activity in computer labs. An individual homework is honored by 30 points (maximally), and the midterm test is honored by additional 30 points (maximally).
