In the field of electronics, what is an IC integrated circuit?

IC (Integrated Circuit), that is, an integrated circuit is a semiconductor manufacturing process, many transistors, resistors, capacitors and other components are fabricated on a small single crystal silicon chip, and the method of multi-layer wiring or tunnel wiring is used The components are combined into a complete electronic circuit. It is represented by the letter "IC" in the circuit (also use the text symbol "N", etc.).

IC integrated circuit classification:
IC can be divided into bipolar integrated circuit and field effect integrated circuit according to the device type, MOS-IC belongs to the latter.
IC can be divided into analog integrated circuit, digital integrated circuit and analog/digital hybrid integrated circuit according to the type of signal processing.
ICs can be divided into small-scale, medium-scale, large-scale, and ultra-large-scale integrated circuits according to their scale (that is, the number of search devices contained therein).
ICs can be divided into low-power integrated circuits and high-power integrated circuits according to their output power.
ICs can be divided into low-voltage integrated circuits and high-voltage integrated circuits according to their working voltage.

There are also low-power integrated circuits, microwave integrated circuits, and so on.
