Active component
From Wikipedia, the free encyclopedia
In electronics, an active component is one that can be used to provide gain in an electronic circuit.
[edit] Examples
- transistors
- operational amplifiers
- vacuum tubes (also known as thermionic valves)
[edit] Nonlinear passive components
The following devices do not fit the definition generally ascribed to active components, but because of their nonlinear responses, designs, histories, and uses in circuits, are sometimes presented alongside active components in textbooks and educational materials.
