Transistors

ransistors serve the purpose of either amplification or switching in most electronic circuits. There are mainly two types of transistors – BJTs (Bipolar Junction Transistors) and FETs (Field Effect Transistors). A BJT is a semiconductor device made up of two p-n junctions connected back-to-back. It can have two types of configurations – PNP or NPN, depending on the doping concentrations. Usually, Silicon is used as a substrate inside a BJT and it is doped according to the voltage and current requirements. A BJT has three terminals – base, emitter and collector. FETs also have three terminals like BJTs but they are made using just one type of material as the main substrate i.e. either p-type or n-type. The three terminals are called gate, drain and source.
