General Description:

The objective of this course is to provide the necessary knowledge of analog electronics to meet two major challenges of connected objects: 

• Guarantee the autonomy of the object compatible with the application in question
• Enable efficient transmission of sensor signals (i.e. provide quality signals at a lower energy cost).

The course covers both analogue electronics devices and operating magnitudes. First, the study of the ideal or real operational amplifier, which responds to the two aforementioned problems of energy management on the one hand and the quality of acquisition and shaping of signals from the physical world on the other hand. From there are presented amplification systems, in particular radio, power supply systems (switch mode power supplies, batteries, energy recovery systems), filters and analog-to-digital conversion.

All courses are supported by SPICE simulations to illustrate the orders of magnitude and operation of the devices studied.

Key words:

Amplification Powerful Energy management Energy recovery Nalog-to-digital conversion Passive filtering Electrical simulation
