Suitable for English-speaking students

Objectives

This curricular unit aims at empowering students with the competences of design and analysis of the main signal conditioning analogue and digital functions/modules, i. e., analogue sampling and multiplexing circuits, filters, tuned amplifiers, oscillators and multivibrators, PLL, A/D and D/A converters, and simple logic gates.  The theoretical study is complemented in the lab classes with the realization of simulation and experimental work, where the design and characterization of circuits is experienced and functional non-idealities are identified.

Learning outcomes and competences

Analysis and design of the main analogue functional blocks found in signal conditioning, A/D and D/A conversion, and telecommunications circuits.

Working method

Presencial

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

Circuit theory, signals and systems theory, Laplace and Z transforms. Analysis of circuits with bipolar and MOS transistors. Attendance of Eletrónica I and Eletrónica II courses.

Program

1- Analogue and mixed-signal (A/D) functions in electronic systems.
2- Signal conditioning. Sampling of analogue signals, types of sample-and-hold circuits and their characterization.
3- Filters: approximation functions; passive filters; active filters; switched-capacitor filters;
4 – Tuned amplifiers. Applications, analysis and design;
5 – Oscillators: oscillation sustaining conditions, Barkhausen criterion. Topologies of oscillators and multivibrators;
6- Frequency synthesiser circuits and Phase-Locked Loop. Static and dynamic characterization and functional;
7- A/D and D/A converters: signal conditioning; characteristic and figures of merit; converters architectures; fields of application of different architectures and converters.
8 – Simple CMOS logic gates.

Teaching methods and learning activities

1- Three-hour weekly tutorial classes where the programme contents are taught with reference to the recommended study elements. Examples are analyzed and problems solved, as well.
2- Two-hour weekly laboratory classes where project, simulation and experimental verification work are performed, making use of electronic CAD tools and bench instrumentation.

Eligibility for exams

The lab classes are of compulsory attendance, being the legislation in force applied regarding the maximum number of admissible absences.
All students will be assessed following this procedure, even those with a special status (working students, students’ association leaders…). Incompatibility situations, in which students cannot attend classes will be analysed on a case by case basis in order to minimize drifting from this process.

Calculation formula of final grade

1- Final Grade (NF) = 60%*Continuous Assessment (AC) + 40%*Exam (E)

The improvement of the E classification can be obtained in the Retake exam.

2 - Continuous Assessment (AC) = 40%*Performance (D) + 60%*Frequency Exam (EF).

3 - Restrictions: The AC classification must be equal to or higher than 8,0 / 20 values; classification E must be equal to or higher than 9,0 / 20 values; NF must be equal to or higher than 9,5 / 20 values.

4 - The Performance component (D) comprises assiduity and assessment of the student performance in carrying out laboratory work. The Frequency Exam (EF) component concerns written mini-tests to be done during the teaching period with questions focusing on the lab work.

The minimum acceptable AC classification is 8,0 / 20 values ​​as a necessary condition for obtaining frequency, being the access to the final exam implicitly not allowed if this objective is not met.

5 - Students with an AC rating of 8,0/20 or more, obtained in past years, can maintain this mark and do not need to attend laboratory classes. NF is calculated as indicated in 1. Students with a frequency obtained before the 2016/2017 academic year must be submitted to a new Performance assessment.

Examinations or Special Assignments

All students are required to fully and objectively complete all assessment components, being not foreseen, in a first instance, other criteria for extraordinary situations. These will be subject to a case by case analysis.

Internship work/project

--

Special assessment (TE, DA, ...)

All students are required to fully and objectively complete all assessment components, being not foreseen, in a first instance, other criteria for extraordinary situations. These will be subject to individual analysis.

Classification improvement

1. Final Grade: exam
2. Performance Assessment: in a next year, subject to individual evaluation taking into consideration the accomplished components.
