Intended learning outcomes (Knowledges, skills and competencies to be developed by the students)

In this course unit are studied the basic semiconductor components: Diodes, Bipolar Junction Transistors (BJT) and Field Effect Transistors (MOSFET).

It intends to develop capacities for analysis, design, and execution of low complexity electronic circuits.

Syllabus

Teaching methodologies

The students attend classes of exposition and discussion of the subjects studied in this course unit, they exercise the acquired knowledge in classes dedicated to the resolution of exercises proposed by the teacher and execute 5 practical works in the laboratory.

Assessment methodologies and evidences

The final classification is obtained by the sum of 60% of the classification obtained in the Theoretical Exam, or in the average of the classifications in three Tests, with 40 % of the classification obteained in the Laboratory, according to the formula (1).

N_F = 0,6N_T + 0,4N_L (1)

were:
-N_F represents the final grade.
-N_T represents the grade obtained in the exam or the average of the tests.
-N_Lrepresents the grade obtained in the Laboratory.


If N_T is less than 8 the student fails in this course unit

If N_L is less than 10 the student fails in this course unit

Attendance system

To obtain attendance the students must submit the reports of the five proposed works.
