Analog integrated circuits have been widely used in various electronic products, playing an increasingly important role. Today I will introduce the characteristics and structure of analog integrated circuits to everyone:
Figure 1-Analog Integrated Circuit
Features of analog integrated circuits:
The first point: the signals solved by analog integrated circuits are successively changing analog electrical signals. Except for the input stage, the signal level in the path is small, so external devices mostly work in a small signal state, and digital integrated paths work normally. Switch status at large signals.
Second point: The efficiency scale of the signal often spreads from DC to high lower efficiency.
The third point: There are many types of components in analog integrated circuits, such as NPN-type tubes, PNP-type tubes, CMOs tubes, film resistors, film library containers, etc., so its creation process is simpler than digital integration.

The fourth point: Analog integrated circuits often have internal and external channels, as long as the process is simple, but the channel performance is inadequate and inconvenient.
Structural characteristics of analog integrated circuits:
The first point is that it is not allowed to make a large amount of warehouse containers, and the channel structure can only adopt the form of indirect meshing.
Second point: The bias DC current of integrated op amps is usually small to increase the power consumption of the path.
Third point: In order to overcome the temperature drift of the indirect meshing path, a differential amplification path is adopted.
The fourth point: a large number of junction transistors or field effect transistors are adopted to form a constant current source, which replaces large resistances.
Fifth point: Adopt the connection method of composite pipe to improve the performance of single pipe. The absolute error of similar components is small, the matching is good, and the performance is relatively uniform, so it is especially suitable for making a path adopting a symmetrical structure.

The above is an introduction to the characteristics and structure of analog integrated circuits. I hope that this article will allow you to better understand its characteristics and structure styles.
