Function of Analog Electronics

The objective of this course unit is to enable students to acquire a basic understanding of analog electronics.

The first section is devoted to linear analog electronics used for conditioning and processing information, particularly that from sensors.

The second part focuses more specifically on the internal structure of the operational amplifiers discussed in the first part, including an examination of the internal architecture of amplifier circuits based on bipolar transistors.

• Acquire the skills needed to analyze linear circuits based on components or active circuits using a synthetic approach, and to use the associated computer tools.
• Know how to select the appropriate models and tools for the studies to be conducted and understand their limitations.
• Understand the basic circuits of analog electronics.
• Be able to design, analyze, and build simple linear circuits using active components or active circuits such as operational amplifiers.
• Develop a scientific and rigorous approach to the studies conducted
