Transistors – FETs, MOSFETs – Single are a type of transistor that uses a field-effect to control the flow of current. They are commonly used in electronic circuits for amplifying or switching signals. These transistors have a single channel and are made up of a metal oxide semiconductor (MOS) structure. They are known for their high input impedance, low power consumption, and fast switching times. They are widely used in applications such as audio amplifiers, voltage regulators, and digital logic circuits.
