Objetivos
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.
Programa
1- Introduction to microelectronics – MOS technology and manufacturing process. Design flow in microelectronics; abstraction levels in the design and simulation of integrated circuits.
2 – Modelling and simulation of MOS circuits: overview of MOSFET’s concepts and operation; MOSFET modelling in weak, moderate and strong inversion; advanced SPICE models.
3 – Technology and physical design of MOS active and passive components: optimisation of MOS circuits design for temperature, parasitics, process parameters variability, current leakaging, power, matching, and geometry. Layout of MOS transistors – simple structures, interdigited, common centroid. Design of passive components: capacitors, resistors, and inductors. Interconnections in VLSI analogue circuits: interconnections physics, RC models and transmission lines. Crosstalk and electromigration phenomena.
4 - Design and layout of basic cells: current and voltage sources, current mirrors, switches, MOS resistors, MOS super transistor.
5 – Design, functional characterization and layout of analogue and mixed-signal modules considering optimization requirements for linearity, symmetrical excursion, frequency response, power consumption and noise: multipliers, operational and transconductance amplifiers (fully-differential and folded cascade architectures and with common-mode feedback), comparators, current conveyor.
6 – Implementation of linear, non-linear, and translinear operators in microelectronics technology
7 – Simulation and sensitivity analysis to functional deviations – variability of manufacturing process parameters, sensitivity analysis and optimum design (design centering), Monte Carlo and corners simulation
8 – Study of particular cases of microsystems involving continuous and discrete time and amplitude circuits: audio systems, wireless, wireline, and optical communication interfaces

Métodos de ensino e atividades de aprendizagem
The approach to be followed resorts to complementing theoretical study with laboratory exercises in order to complement the cycle of circuits' specification, design and functional analysis, physical design and optimization.
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.

Obtenção de frequência
It is mandatory, in accordance to the standard evaluation rules, to attend and participate in at least ¾ of the laboratorial classes.
Fórmula de cálculo da classificação final
The approval in this curricular unit requires obtaining at least 8,0/20,0 points in the final exam and at least 9,5/20,0 points in the weighted average of these two evaluation components. The final classification comprises two components: continuous evaluation (CE) with a weight of 70% and the final exam (E) with a weight of 30%, that is Final Mark=0,7.CE+0,3.E. Continuous evaluation is based in direct interfacing with students and in the evaluation of the projects, presentations and monographies developed by the student.
Provas e trabalhos especiais
Students to whom attending classes is not mandatory, according to current standard evaluation rules, should develop a design project together with the delivery of a final report.
Avaliação especial (TE, DA, ...)
Students with particular status (working students, associations’ leaders, …) have to solve a final exam whose result shall be conjugated with the continuous evaluation mark, maintaining the criteriom Final Mark=0,7.CE+0,3.E to calculate the final mark.
Melhoria de classificação
The improving of the final mark can be obtained, according to current standard evaluation rules, by the solving of a final exam or by the development of a project together with the delivery of a final report.
