Teaching language

Suitable for English-speaking students

Objectives

Students will complement the knowledge previously acquired in the field of semiconductor devices, with the study of the physics and models of active electronic devices, in order to better understand the potential and limitations of the technologies that an engineer has to deal with in the design of biomedical microsystems. After revisiting the functional characteristics and the methodologies of analysis and design of analogue and mixed signal basic cells, students will acquire essential knowledge and the skills to analyze and design capture, processing, conditioning and signal generation circuits in systems for medical electronics applications.

Learning outcomes and competences

Once the students had previously acquired basic knowledge on analogue and mixed-signal circuits and acquired experience in the acquisition and processing of physiological signals using instrumentation and dedicated software tools, the contents of this curricular unit allow complementing the knowledge in the domain of design of signal amplification and processing circuits. Being the treatment of these contents made at the transistor level and being eletronic circuits prototyping processes studied, conditions are met to allow students to assume the design and characterization of biomedical microsystems at a more advanced level.

Working method

B-learning

Teaching methods and learning activities

The methodology to be followed is that of complementing the theoretical study with the lab approach in order to complement the cycle of specification, design, functional analysis, physical design, and optimization of the circuits. In the tutorial classes the topics are presented with reference to the adopted study material. Examples are also studied and problems are solved. In the lab classes bench work involving simulation, making use of CAD tools, and experiments will be made. The first assignments will be of a tutorial type, being progressively adopted an approach that calls for the autonomous design capacity of the student. The final work will be the project of a circuit after a set of specifications which feature common requirements of biomedical microsystems.

The tutorial classes will be dedicated to the presentation of the different contents seeking in each topic to relate the presented electronic circuits with their versions and characteristics in the specific field of biomedical systems. In the final classes dedicated to the study of specific cases, each group will be in charge of preparing the study and presentation in the class of the case it has been assigned with.

The lab work will be carried out by groups of two students in order to stimulate the team cooperation in the study, analysis and realization. The assignments will be defined so that the presentation of the different topics in the tutorial classes is complemented with the simulation and experimental verification. For each one of the assignments the students will prepare a short report where the raised questions are answered and a critical analysis of the obtained results is made.

In the final development project each group will have to resort to a review of pertaining literature in order to obtain the best solution to comply with the specifications of the assigned problem and will have to prepare, besides the report, an oral presentation to be made in a dedicated session, of all developed work as well as of the obtained results.

Eligibility for exams

The continuous assessment component is based on the individual  interaction with students in the lab classes and in the assessment of the practical assignments. To be admitted to exams, students have to reach a minimum average grade of 8/20 in the continuous assessment component. Laboratorial classes are mandatory and students cannot miss them in a number higher than that allowed by the rules.
All students will be assessed with this procedure, even those with a special status (working students, students’ association leaders…). Any situation, in which students cannot attend to classes will be analysed on a case by case basis in order to minimize drifting from this process.

Calculation formula of final grade

Final Grade = 60%*Continuous Assessment + 40%*Exam- Students have to reach a minimum grade of 8 out of 20 in the exam and a minimum grade of 9.5 out of 20 in the final grade .

The distributed assessment comprises the evaluations of the individual aptitude in the realization of the lab work (30%), and the quality of results and submitted reports (70%).

Students who attended this course in a previous year and reached a minimum grade of 8 in the Continuous Assessment component, do not need to attend lab classes. Final grade will be calculated as above.

Examinations or Special Assignments

All students have 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.

Internship work/project

Development of a small project in the last third of the lective period.

Special assessment (TE, DA, ...)

All students have 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. Continuous Assessment (in a next year): subject to individual evaluation taking into consideration the accomplished components.
