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.

Teaching methods

Due to the COVID-19 crisis, the information in this section is particularly likely to change.

Traditional lectures and exercises :
- lectures ;
- problem solving in audience.
Directed practical work. Analogue electronics (obligatory) :
- experimental study of basic circuits ;
- LTSPICE simulation of circuits ;
- report after each session.
Project : developing an acquisition system with an FPGA or RaspberryPi :
- implementation of a serial reading protocol (type I2C, USB, ...) ;
- tutorials provided by teachers / assistants.
Evaluation methods

Due to the COVID-19 crisis, the information in this section is particularly likely to change.

The evaluation is based on :
Analog Electronics
  • -Laboratory reports (25%) ;
  • Written exam : 5 or 6 questions + 3 problems (25%) ;
Digital Electronics
  • Exercices during lectures (25%)
  • Presentation of an acquisition project : oral questioning (25%).
Depending on the sanitary conditions the evaluation methods would be adapted to non-presential examinations.
