A bipolar junction transistor (BJT) is a current-driven semiconductor element that uses a small amount of current to control the flow of a larger electric current. In contrast to a unipolar transistors, such as a field-effect transistors which uses only one kind of charge carrier, a BJT uses both electrons and electron holes as charge carriers. BJT Transistors can be used to amplify weak electrical signals and are also used as oscillators or as switches.
Integrated circuits are a combination of wide-ranging electronic circuits integrated into a semiconductor chip. They are designed to perform the advanced computational functions which are used in key processor programs. Let's learn more about these fascinating integrated circuits.
