This course covers 2 basic devices of analog electronics: the diode and the operational amplifier (OP-AMP).
Knowledge of the characteristics and behaviour of each of these devices makes it possible to integrate them, while combining them, into more complex circuits in order to achieve new electronic functions.
The main functionalities studied are in the area of rectifier (diodes), as well as various elementary function blocks based on OP-AMPS: amplifiers, filters, oscillators…
The devices and circuits will be studied during tutorials sessions, practical Work sessions, but also with an electronic circuit simulation software based on the SPICE engine.
We will focus on the characteristic of a diode and its operating point, its use in rectifying, filtering and voltage regulator, but also in various applications such as clipper circuits, voltage multiplier circuits,...

Next, we will focus on OP-AMPS basic assemblies: inverting and non-inverting amplifier, summing amplifier, different kind of filters (Rauch, Sallen-Key,..), comparator and Schmitt triggers, integrator, oscillators..., further combining these primary circuits to provide new analog functions.
Practical Work perfomed during "Physics lab training" sessions (physics 3&4): Diode Current - Voltage characteristics, load line analysis and operating point. Full wave bridge rectifier, capacitor filtering. Clipping circuit, voltage multiplier circuit (3h00).
Op-Amps circuits : inverting and non-inverting amplifier, summing amplifier, comparator and Schmitt trigger, precision rectifier (super diode), integrator, Wien bridge oscillator (3h00).
 

At the end of this subject you will be able to :

• Design the schematic of simple electronic functions, then analyze the performance of the circuit (output signal in response to an applied input signal), such as rectifiers, operational amplifier circuits (amplifiers, filters, oscillators...), etc....
• Analyze circuits theoretically, but also by SPICE simulation algorithm and software, where the observation of signals at different nodes of the circuit will allow to understand how a circuit operates.
