In order to achieve the best understanding of syllabus contents, the following background is needed:
• Signal processing
• Circuit theory
• Electronic devices
• Analog CMOS circuits
The aim of this syllabus can be split into two goals:
• Introduction to the design of A/D and D/A converters in CMOS technologies
• Hands-on experience on the high-level description languages used for the simulation of these mixed integrated circuits.

1.5. Lab proposal: My Delta-Sigma ADC in 2.5um CMOS technology (CNM25)
Chapter 2. ADC architectures and CMOS circuits
2.1. ADC classification
2.2. Flash techniques

Progressive evaluation of the overall mark is based on the following weights:
• Two partial exams (25%+25%)
• Lab report (40%)
• Solved exercises (10%)
The above evaluation scheme is only applicable when marks for first and second items are greater or equal to 5/10.
If the combined mark for partial exams is less than 5/10, students can re-take a single exam (remedial exam) to recover that 50% of the overall mark.
Lab work (including sessions and report) is mandatory to pass evaluation and it can not be recovered.
Finally, students will be considered as absent (i.e. "No Presentat") if they do not attend lab sessions OR they are not present at the required exams.
Any change on the above evaluation method will be communicated in advance.
