Transistors include bipolar transistors, metal-oxide-semiconductor field-effect transistors, insulated-gate bipolar transistors (IGBT), etc. They can function as a variable switch, controlling the flow of current based on the input voltage or current. Therefore, transistors can act as current switches, and their switching speed can be extremely fast. As a solid semiconductor device, transistors can be widely applied in demodulation, rectification, amplification, switching, voltage regulation, signal modulation, and many other fields.
