Active components

Active components are also called (active devices): electronic components that require power to achieve their specific functions, mainly including electron tubes, transistors, integrated circuits, etc. Generally used for signal amplification, conversion, etc. If an electronic component has a power source inside it when it is working, the device is called an active device. This is an electronic device that requires a source of energy to perform its specific function. From the perspective of physical structure, circuit function and engineering parameters, active devices can be divided into two categories: discrete devices and integrated circuits.
