Analog and digital electronics
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.

LPHYS1221 for the students enrolled in the Bachelor in physics who wish to follow this teaching unit within the additional module in physics. Having followed LPHYS1201 is an asset.
No prerequisites for students who have obtained a Bachelor's degree in physics and who therefore already have a basic knowledge of :
- circuit theory,
- the complex algebra and Laplace transform.
Main themes
This teaching unitis designed to familiarize the student with the basic aspects of electronic equipment in modern metrology. It is divided into two parts. The first part deals with the essential points of linear electronics in semiconductors and small signals. The second part is dedicated to an introduction to digital electronics and data acquisition systems. Both parts should be followed in parallel and the links between these two parts will be done during practical work and during a personal project.

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

1 a.     Contribution of the teaching unit to the learning outcomes of the programme (PHYS2M and PHYS2M1)
AA1: A1.1, A1.5
AA2: A2.5
b.    Specific learning outcomes of the teaching unit
At the end of this teaching unit, the student will be able to :
1. describe the operating mode of the basic electronic, analog and digital components and its limitations ;
2. simulate with LTSPICE software the response of the basic electronic circuits ;
3. analyze and calculate the basic assemblies commonly used in physics in the reading of sensors / detectors ;
4. analyze and draw a finite state machine ;
5. link an electronic data acquisition system to the computer using a simple communication protocol.


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”.
