Design and Architecture of analog electronic systems
Note from June 29, 2020
Although we do not yet know how long the social distancing related to the Covid-19 pandemic will last, and regardless of the changes that had to be made in the evaluation of the June 2020 session in relation to what is provided for in this learning unit description, new learnig unit evaluation methods may still be adopted by the teachers; details of these methods have been - or will be - communicated to the students by the teachers, as soon as possible.

Students are expected to master the following skills: continuous-time signal representation both in time and frequency domains, mathematical system representations (transfer function, impulse response, stability, filtering), principles and properties of Fourier and Laplace transforms, analysis of electrical circuits based on passive components (R, L, C), in DC, transient and AC regimes, understanding of general behavior of operational amplifiers, diodes and transistors with the associated basic electronic circuits, as they are covered within the courses LFSAB1106, LELEC1370 and LELEC1530.
Main themes
The world we live in is getting more and digital with electronic embedded systems surrounding us and communicating with the cloud. However, the physical world is analog in essence. The digital embedded systems thus need analog functions to interact with the physical world, its users, the cloud, the energy sources, as well as between themselves. This is done through sensors, actuators, user interfaces, power management units, wireline and wireless communications. Digital systems also rely on key analog functions performed internally for efficient operation: memories, clocking and voltage regulation. In this course, we study the architecture of the key analog electronic systems performing these functions.
Within the ELEC/ELME formation, this course presents analog system architectures as a complementary to ELEC2531 course on digital system architectures. It serves as a basis for the courses on integrated-circuit synthesis (ELEC2650, ELEC2570 and ELEC2620).

At the end of this learning unit, the student is able to :

1 a. Contribution of the activity to the learning outcomes of the program
  • AA1 Knowledge base : electronic concepts (AA1.1), simulation and CAD tools (AA1.2-3).
  • AA2 Engineering skills: problem analysis (AA2.1) and solution comparison (AA2.3).
  • AA3 R&D skills : find appropriate references on the existing solutions in the field of the flipped class topic (AA3.1).
  • AA5 Communication skills: oral communication (AA5.3, AA5.6).
  • AA6 Professional skills: use of appropriate standards (AA6.1), critical evaluation of technical solutions (AA6.3) and autonomous learning (AA6.4).
b. Learning outcomes
After this course, the electrical engineers in circuit and systems should be able to:
  • identify the key performance metrics of an analog function in a given application context,
  • explain the operation of typical analog system architectures,
  • qualitatively model the performance with respect to the architecture,
  • evaluate the performance of typical analog system architectures with SPICE simulations.

The contribution of this Teaching Unit to the development and command of the skills and learning outcomes of the programme(s) can be accessed at the end of this sheet, in the section entitled “Programmes/courses offering this Teaching Unit”.
  • Noise in analog circuits
  • Opamp-based circuits
  • Analog filters
  • Voltage and current references
  • Voltage regulators
  • Memories (it time allows)
  • CMOS imagers
  • Oscillators
  • Phase-locked loops
  • High-speed serial I/Os
Teaching methods
The course is organized as follows:
  • lectures on generic  analog concepts and building blocks,
  • exercise sessions on these concepts and building blocks,
  • flipped classes about typical analog applications and associated specific architectures of analog systems, these classes are based on a reading at home and a group challenge in class with a SPICE simulation tool,
  • seminar given by an expert from the industry (if time allows).
Evaluation methods
The evaluation is based on the group challenges during the semester, an individual written exam and an invidual practical exam with the simulation tool.
