Reading time: <1 minut The polarization of a transistor involves the construction of a circuit so that the transistor usually operates in direct polarization and at certain parameters. For this, the junction BE (base-emitter) must be polarized directly and the junction CB (collector-base) must be polarized inversely.
Reading time: <1 minut The bipolar junction transistor (BJT) is a semiconductor device with two junctions in NPN or PNP sequence. The three areas are called emitter (E), base (B), collector (C). It is used in both digital and analog electronic circuits, usually to amplify or transmit an electrical signal.
Reading time: <1 minut The paper presents topics in semiconductor physics, physical and applied electronics, which the author considered among the foundations of radioelectronics, ie that part of electronics having as object of study the theoretical and practical problems related to radio-electrical signal processing.
Reading time: 2 minute Transistors have transformed the world of electronics and have had a huge impact on the design of electrical and electronic devices, especially the computer. By replacing bulky and inappropriate tubes with transistors, computers can now perform the same functions, using less power and saving space. The name transistor comes from "trans" which stands for transmitter and "zistor" which stands for resistor.
