Special Issue Description

A bipolar junction transistor (BJT) is a type of transistor in which electrons and electron holes are used as charge carriers. A unipolar transistor, such as a field-effect transistor, on the other hand, uses only one type of charge carrier. A bipolar transistor uses a small current injected at one of its terminals to control a much larger current flowing between the terminals, allowing the device to amplify or switch. BJTs make use of two junctions between two types of semiconductors, n-type and p-type, which are regions in a single crystal of material. The junctions can be formed in a variety of ways, including changing the doping of the semiconductor material as it grows, depositing metal pellets to form alloy junctions and diffusion of n-type and p-type doping substances into the crystal. Junction transistors quickly surpassed the original point-contact transistor in predictability and performance. Diffused transistors, along with other components, are components of analog and digital integrated circuits. Hundreds of bipolar junction transistors can be manufactured at a low cost in a single circuit. Because of the wide variety of BJT types available, as well as its high transconductance and output resistance compared to MOSFETs, the BJT continues to excel in some applications, such as discrete circuit design. Bipolar transistor integrated circuits were the primary active devices in a generation of mainframe and minicomputers, but most computer systems now use field-effect transistor integrated circuits. Bipolar transistors are still used in signal amplification, switching, and digital circuits.
