The transistor’s reliability, low price and size have made electronics common and available to everyone. These devices can range from a single transistor that can be used as a switch or amplifier to an Integrated Circuit (I.C.) that may contain millions of transistors on a single chip, and which powers a computer. A bipolar junction transistor, hereafter referred to as BJT, is a kind of transistor that uses two types of a doped semiconductor material. The BJT will have two PN junctions and will use three connections to control the transistor. These connections are called the base, the emitter and the collector. This material is known as P material or N material. The two materials
