Presentation

The CU is devoted to the teaching of the working principles/use of devices based on semiconductors and integrated circuits. Students will be trained to design and implement analog and digital circuits as well as to understand the functioning of electronic instruments and sensors.

Sustainable Development Goals

Learning Goals

In this course unit, basic knowledge on analogic and digital electronics that will allow the students to analyze and design reasonably complex circuits is taught. The syllabus includes the study, from the logic point of view, of the basic building blocks in digital electronics. These basic blocks are used to develop more complex combinatorial circuits. The techniques for analysis and design are also taught. The analysis and design of sequential circuits is then lectured. Concepts of programmable logic and its respective hardware are also presented, so that the students acquire the capacity to explore the latest developments in digital circuits technology.

Teaching Methods

The teaching method is based in theoretical, practical and laboratory classes. Strong emphasis is placed on projecting, simulating and implementing logic circuits.

The assessment is based on 2 parts: Theoretical (70%) and Laboratorial (30%)
Assessment elements are graded using the interval [0,20].
The theoretical part: 2 Tests or a Final Exam: Minimum grade 9.5
[F1] Test 1 - Minimum grade 9.0 (35%)
[F2] Test 2 - Minimum grade 9.0 (35%)
[Ex1] Final Exam 1 (70%)
[Ex2] Final Exam 2 (70%)

The Laboratorial part has minimum grade 9.5
[L] Laboratory (30%)
The labs activities are mandatory. A practical exam on the labs activities can be requested if the minimum grade is less than 9.5

[NF] Final Grade: NF = Max{(F1 + F2)/2; Ex1; Ex 2}×0.7 + L×0.3

If NF>= 9.5: Approved
If NF< 9.5: Failed
Student tutoring available outside the class, once a week in slot of 2 hours. Email and on-line platform available for basic questions or for rescheduling the tutoring timetable in order to suit each student
