7. Conclusion

The amplification of electrical signals is essential for all systems that need to capture analog information. The most important of these is low-amplitude voltage amplification.

This article covers all the concepts essential to understanding and designing low-frequency amplifiers. It provides a fundamental foundation for engineers working in electronics and lays the groundwork for exploring numerous fields of application related to engineering sciences: filtering [E 115] , conversion

Standards and norms

There are numerous norms and standards in this field. They are linked to international organizations, including:

IEC (International Electrotechnical Commission): international standardization organization in the fields of electricity, electronics, electromagnetic compatibility, and micro- and nanotechnologies. This organization defines, in particular, the characteristics...

Regulations

Regulations concerning voltage boosters depend on their use, power, operating environment (professional, medical, domestic, etc.), and their potential impact on safety and communications. Here is an overview of the main laws, decrees, and standards applicable in France and Europe:

general framework in Europe, CE marking: all electrical and electronic equipment, including voltage...

Patents

As current needs are mainly focused on autonomous embedded systems, for example for AI (Artificial Intelligence), recent patents on voltage amplifiers concentrate on miniaturization (SoC – ), reduced power consumption, low-noise and wide-bandwidth amplification, as well as PVT compensation techniques (Process, Voltage, Temperature) and automatic calibration techniques.

Here are some examples of patents...
