Author(s): SAL Maftunzada
Abstract: A transistor is an electronic component that amplifies signals or acts as a switch in a circuit. Transistors enable us to control, divert or even reverse the amount of current flowing through a circuit. When we talk about amplifying signals, we're talking about the amount of power (voltage x current) that flows through the circuit. Transistors are used in the complex switching circuits that make up all modern telecommunications systems. A transistor can act as a switch or gate for electronic signals, opening and closing an electronic gate several times per second. Transistors are used as switches, amplifiers, voltage stabilizers, etc. in electronic circuits. A typical transistor consists of three n-type and p-type semiconductor crystals placed side by side. The abbreviations PNP and NPN and technical symbols are used to represent transistors on drawings. The arrangement of transistors in electronic circuits is common emitter, common base and common collector. In this article, while dealing with the general characteristics of transistors such as transistor construction, bias, load line, calculations related to bias and its applications in simple amplifiers, we also discuss how each one works. Before the invention of the transistor in the first half of the 20th century, electronics depended on vacuum tubes, which were bulky, expensive, and uneven, required a lot of power, and produced a lot of heat. The invention of transistors led to modern electronics, making smaller and more powerful electronic devices possible because transistors require little power, don't generate much heat, and are very reliable. Small transistors can be used in complex integrated circuits, making it possible to pack a lot of computing power into a small package.
