Objectives

To endow the students with the concepts and techniques of analysis and design of differential, multistage amplifiers, and of linear and nonlinear circuits to which they are applied. The operation of transistors in switching mode is also an object of study in the context of synthesis and behavioral analysis of basic logic circuits, thus completing the basic training of students in electronics, in its most fundamental aspects.

Learning outcomes and competences

At the end of this curricular unit, students should have strengthened their technical knowledge in the field of electronics and improved their personal and professional skills, especially in engineering thinking and problem solving, and students should be able to carry out experimentation and working in group.

Working method

Presencial

Pre-requirements (prior knowledge) and co-requirements (common knowledge)

Fundamental electronics (Electronics 1), including circuit analysis with diode and basic single-transistor amplifiers — MOSFET and BJT.

Program

1- Frequency response of basic amplifier configurations.
2- Differential pair.
3- Multistage amplifier components and small- and large-signal analysis methods (with and without active load) - AmpOp.
4- Analysis of a commercial AmpOp - x741, and its principal characterization parameters.
5- Power output stages (classes A, B and AB).
6- Analysis of feedback amplifiers in their different forms.
7- Stability analysis and compensation of feedback amplifiers.
8- Functional circuits with AmpOps.
9- Operation of electronic devices under switching.
10- CMOS logic circuits - Inverter, NAND and NOR - basic characterization.

Both bipolar and MOSFET transistors are included in the program.

Teaching methods and learning activities

- Lectures (T) for delivery of content and discussion, where the subjects are treated with the presentation of illustrative practical examples, in a logic of active learning, interleaved with classes for training and discussion of circuit analysis techniques, synthesis and problem solving.

- Laboratory Practice (PL) classes where the learned concepts are applied in the realization of a set of experimental works that includes circuit design aspects

Eligibility for exams

- Attendance of lab classes is mandatory. The number of permitted absences from lab class is very limited and follows University rules.

- If a student skips an assignment, even if adequately justified, the student still have to perform that assignment during another lab class or during extra-curricular time. However, students have to be authorized by the professor and supervised by the laboratory responsible

- Students can only attend the exam if a minimum grade of 9 out of 20 is acheived in the laboratory-class component.

Calculation formula of final grade

1. For ordinary students in first enrollment:

The final classification (FC) follows the following formula:

FC = 0,1×MT1 + 0,1×MT2 + 0,5×E + 0,3×LP

2. For ordinary students in first registration who have missed a midterm with a justification accepted by the professor responsible for the course, the percentage of that quiz is added to the final exam.

3. For students on a special regime or ordinary students who have already obtained approval in the laboratory component of the curricular unit and have not expressly requested access to the midterms, the following formula applies:

FC = 0,7×E + 0,3×LP

In any of the cases indicated above, the grade of the laboratory component (on a scale of 0 to 20) is limited to the classification of the final exam plus 4 values:

LP = min {LP, E + 4}

4. The weight of the mark correspondent to the distributed component evaluation is kept for both the regular and second period exams.

(NOTE: MT1 = Midterm 1, MT2 = Midterm 2, E = Exam, LP = Laboratory Practice.)

Examinations or Special Assignments

1. Two midterms along the semester. Typically the first between the 5th and the 6th week and the second between the 9th and 10th week of the semester.

2. Students will be assessed on their performance and participation in laboratory classes, by their effort and engagement (30%) as well as by answering to a quiz at the end of each assignment (70%).

3. Special period exams (degree completion or others) follow the rule number 3 applicable to regular period exams.

Internship work/project

Does not apply

Special assessment (TE, DA, ...)

1. Lab component is mandatory for all students.

2. Special regime students are exempt from performing midterms. However, they can request to perform them.

Classification improvement

1. In case of registering to a final exam for grade improvement, if made in the same school year, the rules are the same as for  the period of final exams.

2. In case of grade improvement in a subsequent school year, the exam will weight 70% and the lab grade, already taken, weights 30%.

In all cases, the lab-component grade (in a 0 to 20 scale) is limited to the final exam grade plus 4 points (out of 20) — LP = min {LP, E + 4}.
