Modeling and implementation of analog and mixed analog/digital circuits and systems on chip
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.

Main themes
Over the last decades, integrated circuits have evolved from chips with a single function to complex systems on a single silicon chip. Such modern systems-on-chip (SoCs) features digital signal processors, microcontrollers, analog and RF circuits to provide the necessary interfaces to the physical world made of sensor signals, audio/video interfaces, electronic signals or wireless communications. These analog/mixed-signal (AMS) systems require the co-integration, co-design and co-verification of analog and digital circuits on the same CMOS technology platform. In this course, we will study the implementation of mixed analog/digital circuits with the help of behavioral modeling, as an essential tool within the design flow of AMS systems.
This course concludes the ELEC formation in electronic circuits and systems.

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)
AA2 Engineering skills : analysis and modeling of an electronic system,
AA3 R&D skills : find appropriate references on the existing solutions in the field of the course's project (AA3.1)
AA4 Project management
AA5 Communication skills : analysis and writing of a technical datasheet (AA5.3-5.5).
b. Learning outcomes
After this course, the electrical engineers in circuit and systems should be able to:
  • critically compare analog and digital circuit solutions within a given applicative system context with respect to signal quality, power consumption, cost and flexibility,
  • analyze the sources and propagation of analog non-idealities into a mixed-signal chain,
  • generate appropriate abstractions for analog building blocks and model their behavior at high level in Verilog-AMS language,
  • setup an appropriate methodology for designing, simulating and verifying a mixed-signal system from specification phase to block partitioning to physical implementation,
  • co-simulate and co-verify analog blocks with a digital circuit in Verilog to mitigate the limitations of analog blocks and to extract specifications for the mixed-signal circuit implementation,
  • analyze industrial-level datasheets of an electronic system in the context of a design project ,
  • analyze scientific-level papers in the field of electronic circuit and systems.
