4. Lab VIII: Experiment VII The Bipolar Junction Transistor (BJT) Characteristics The bipolar junction transistor (BJT) is a three-terminal solid state device widely used as an amplifier (or switching) device. It consists of two n-type materials sandwiched by p-type material (npn) or two p-type and n-type. The terminals (sections) are known as emitter E, base B and collector C. Two currents and two voltages uniquely describe the behavior of the device. The third current/voltage can be determined through KCL/KVL. See...
