Objectives

Analogue Microelectronics aims empowering students with the abilities and competences to design analogue and mixed-signal circuits in MOS sub-micron technologies. Following the study of the fundamental physics and manufacturing process principles, the simulation and modelling of active and passive components is discussed taking into consideration their implementation in silicon substrates and signals’ amplitude and frequency operating conditions. Afterwards, one proceeds with the design simulation and layout of different analogue and mixed-signal functional modules using dedicated CAD tools.

Learning outcomes and competences

Deepening of the knowledge on the physics and functional principles of semiconductor devices; get acquainted with fabrication technologies and layout of active and passive devices of MOS circuits; systematic approach to the design of circuits with MOS transistors in different operating modes; understanding of the restrictions and limitations imposed by non-idealities resulting from the circuits’ own functional characteristics e those resulting from implementation and manufacturing processes; analysis of small systems where analogue and mixed-signal circuits and blocks are used.

Working method

Presencial

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

Knowledge of: circuits’ theory; analysis of basic circuits with diodes and transistors, feedback theory, frequency response and compensation, synthesis and implementation of continuous discrete time filters, A/D and D/A converters’ architectures, oscillators and frequency synthesizers

Teaching methods and learning activities

The approach to be followed resorts to complementing theoretical study with laboratory exercises in order to complete the cycle of specification, design and functional analysis, physical design and optimization of the circuits.

In the set of tutorial and laboratory classes one will seek, for each subject, to obtain a balance among theoretical study, circumstantial analysis of functional and sizing particularities, and use of CAD tools. In the theoretical classes subjects are presented with reference to pointed-out study material, examples are analyzed and problems solved. Students’ participation is motivated with the preparation and presentation in the class of short synthesis works, monographies, or project results. In laboratory classes students will have the opportunity to get familiar with the use of microelectronics CAD tools.

One can consider that the main teaching and learning methods involved in this approach include, at different levels: lecturing, class discussion, case studies, tutoring, and project based learning.

Eligibility for exams

It is mandatory, in accordance to the general evaluation rules, to attend and participate in at least ¾ of the laboratorial classes.
The approval in this curricular unit requires obtaining at least 9,0/20,0 points in the final exam and at least 9,5/20,0 points in the weighted average of exam and continuous evaluation components.

Calculation formula of final grade

The final mark comprises two components: continuous evaluation (CE) with a weight of 70% and the final exam (E) with a weight of 30%, i. e., Final Mark = 0,7xCE + 0,3xE.
Continuous evaluation is based on the assessment of students' attitude and performance in the classes and on the evaluation of projects, presentations and reports developed by the student.

Examinations or Special Assignments

Students to whom attending classes is not mandatory, according to current general evaluation rules, should develop a design project together with the delivery of a final report.

Special assessment (TE, DA, ...)

Students with particular statute (working students, associations’ leaders, …) have to solve a final exam whose result shall be conjugated with the continuous evaluation mark, maintaining the criterion Final Mark=0,7.CE+0,3.E to calculate the final mark.

Classification improvement

The improving of the final mark can be obtained, by the realization of an exam (to be done in the normal exams’ season of the next academic year), which can be theoretical or laboratory, or by the development of a project together with the delivery of a report for the improving of the continuous evaluation.
