Digital integrated circuit
It is an integrated circuit that performs arithmetic and logic operations on discrete digital signals (such as binary codes represented by two logic levels of 0 and 1). Its basic unit is a logic gate circuit, including memory (DRAM, Flash, etc.), Logic circuits (PLDs, gate arrays, display drivers, etc.), micro components (MPU, MCU, DSP).

Analog integrated circuit
Mainly refers to an integrated circuit composed of analog circuits composed of resistors, capacitors, transistors, etc., which are integrated to process analog signals in the form of continuous functions (such as sound, light, temperature, etc.), including general analog circuits (interface, energy management, signal conversion, etc.) Etc.) and analog circuits for special applications.

Optoelectronics
For ordinary people, the optoelectronics industry is the most common mobile phone screen that we see every day. Whether it is ordinary LED or OLED, it belongs to optoelectronics . Some other applications are laser devices, transmitters used in printers, optical fibers, etc. In fact, if it is a simple application, optoelectronic technology is still relatively simple.
sensor
For example, there are pressure sensors in your mobile phone, temperature sensors in your car, medical measurement, diagnostic sensors, gas sensors used by environmental departments, and sensors for detecting atmospheric PM2.5, and smoke installed in office buildings for fire prevention. Sense and so on. In short, the function of the sensor is to convert information such as pressure and temperature into electrical signals.
Discrete device
The integrated circuit (IC) we talked about earlier is about how the black box above was created. But on the system board, there are still some places where diodes, transistors, resistors, capacitors, logic devices, etc. are inserted (of course, the positions I marked in the figure may not be accurate, just to illustrate this example), these are what I think are discrete devices .
