Analog-to-Digital and Digital-to-Analog Converters-MEET

T - Theoretical; TP - Theory and practice; PL - Laboratory; S - Seminar; OT - Tutorial.

• Learning outcomes of the curricular unit

  A student completing this course unit should be able to:

  1. Understand and discuss the behaviour of the different studied converters.
  2. Chose and use the appropriate converter for a given application.
  3. Compare and test different converters for their inclusion on an electronic system.
  4. Design and draw converters using the professional tool Cadence.
  5. Learn the design flow to carry on chip the converter.
• Syllabus

  I. Fundamental concepts of A/D and D/A converters. Codes and quantization and sampling theory. Static Characteristic and static errors. Dynamic errors.
  II. DAC architectures: Kelvin divider, thermometer, R-2R and segmented.
  III. ADC architectures: Comparator, High-speed, Integrating and counting, Sigma-Delta
  IV. Digital Circuits: Static CMOS, Transmission Gates.
  V. DACs and ADCs tests: static and dynamic performance. IEEE1241 standard

• Demonstration of the syllabus coherence with the curricular unit's objectives

  This unit, being optional, centralizes its approach on one of the most important blocks existing in many of the electronic systems in our days. Students are challenged to study and present some of the themes (I, II e III)  in the context of the class, being questioned by the teacher and by their colleagues for clarification and understanding of exposure. The understanding of the topics by each student is deepened by the design and realization of a converter in integrated circuit, using the professional tool Cadence.

• Teaching methodologies (including evaluation)

  Theoretical and practical teaching is planned during the semester in 30 lectures that correspond to 67.5 of contact hours (15 lessons of 3 hours and 15 of 1.5 hours). The total student working hours is 160. The lectures are intended for presentation of topics and practical examples. Learning outcomes (1) and (2) are individually assessed through presentations with discussion and one project throughout the semester. During the monitoring of the project are assessed learning outcomes (3), (4) and (5). The project has, at the end of the semester, a public presentation, open to all who are interested (teachers and students).

• Demonstration of the coherence between the teaching methodologies and the learning outcomes

  In theoretical and practical sessions are covered syllabuses that correspond to the learning objectives 1 to 2. The use of Cadence tools enables student contact with the technical design and drawing, used in design companies of integrated circuit, reaching the learning objectives 3, 4 and 5.
