Low frequency electronics - WFME1021

Goal(s)

Part 1 – Fundamental concepts (low frequency)
Know how to equate a simple electronic circuit (consisting of generators and resistors) in DC mode using basic laws and theorems (Ohm's law, law of voltage and current dividers, superposition theorems, Millman, Thevenin).
Introduction and presentation of the operational amplifier and its basic set-ups (inverting, non-inverting)
Presentation of the harmonic regime and the notion of complex impedance. Extension of the use of the previous theorems to the harmonic regime. Bode diagrams and introduction to the concept of power spectral density

Part 2 - Basic functions of an electronic instrumentation chain
To know the main functions used in an electronic instrumentation chain (low frequency)
DC or switching power supplies. Frequency filtering (synthesis of passive or active filters) Digitisation with sampling (Shannon's theorem) and A/D and D/A conversions
Microcontroller architecture
Presentation of semiconductor components: diode (rectification), LED, photo detector and transistor

Part 3 - Electronic circuit design
Knowledge of the rules and technologies for designing and producing electronic printed circuits (chemical techniques, milling, transferring conductors or components).
Box dimensions and electronic component technology.
Presentation of electronic routing software, which can be linked to electronic simulation software used in the two electronics modules (fundamental and applied).
