Most transistors are made from very pure silicon, and some from germanium, but certain other semiconductor materials are sometimes used. A transistor may have only one kind of charge carrier, in a field-effect transistor, or may have two kinds of charge carriers in bipolar junction transistor devices.

What is the base of transistor?
The base of transistor is lightly doped. A transistor is an electronic component that is used in circuits to either amplify or switch electrical signals or power, allowing it to be used in a wide array of electronic devices. Base – This segment is at the center of the transistor. It is thin and lightly doped.
How transistor is formed?
The Transistor is a three terminal solid state device which is formed by connecting two diodes back to back. Hence it has got two PN junctions. Three terminals are drawn out of the three semiconductor materials present in it. ... The three terminals drawn from the transistor indicate Emitter, Base and Collector terminals.
What exactly is a transistor?
A transistor is a device that regulates current or voltage flow and acts as a switch or gate for electronic signals. Transistors consist of three layers of a semiconductor material, each capable of carrying a current. ... A transistor regulates current or voltage flow and acts as a switch or gate for electronic signals.
What are the terminals of transistors?
A transistor is an electronic device that contains three terminals named emitter, base, and collector.
What is a transistor emitter?
Emitter: Emitter terminal is the heavily doped region as compared two base and collector. This is because the work of the emitter is to supply charge carrier to the collector via the base. The size of the emitter is more than base but less than the collector.
How is a BJT made?
A BJT consists of three differently doped semiconductor regions: the emitter region, the base region and the collector region. These regions are, respectively, p type, n type and p type in a PNP transistor, and n type, p type and n type in an NPN transistor.
How are BJT created?
BJTs are created by layering p-type and n-type silicon to form a three-layer “sandwich”: The base, to which a small starting current is attached.
What is a transistor for dummies?
A transistor is an electronic component that is used in circuits to either amplify or switch electrical signals or power, allowing it to be used in a wide array of electronic devices. A transistor consists of two PN diodes connected back to back. It has three terminals namely emitter, base and collector.
How does a transistor amplify?
A transistor acts as an amplifier by raising the strength of a weak signal. The DC bias voltage applied to the emitter base junction, makes it remain in forward biased condition. ... Thus a small input voltage results in a large output voltage, which shows that the transistor works as an amplifier.
What is an example of a transistor?
An example of a transistor is something combined in large numbers with microcircuits into a single circuit board and used in a computer. A small electronic device containing a semiconductor and having at least three electrical contacts, used in a circuit as an amplifier, detector, or switch.
What are the three main connections in a transistor?
The Bipolar Transistor basic construction consists of two PN-junctions producing three connecting terminals with each terminal being given a name to identify it from the other two. These three terminals are known and labelled as the Emitter ( E ), the Base ( B ) and the Collector ( C ) respectively.
How many terminals are in transistor?
Transistor – a three-terminal device for which the voltage or current at one terminal controls the electrical behavior of the other terminals.
What is a transistor circuit?
transistor, semiconductor device for amplifying, controlling, and generating electrical signals. Transistors are the active components of integrated circuits, or “microchips,” which often contain billions of these minuscule devices etched into their shiny surfaces.
How are transistors Labelled?
The leads are labelled base (B), collector (C) and emitter (E). These terms refer to the internal operation of a transistor but they are not much help in understanding how a transistor is used, so just treat them as labels. A Darlington pair is two transistors connected together to give a very high current gain.
How are transistors labeled?
Bipolar junction transistors are the most commonly used type. To help identify them, transistors are labeled with number and letters on their casings. Transistors are labeled according to the numbering system that is used. ... An ordinary bipolar transistor has three leads, so the first digit for it will be 2.
What are the four transistor circuits?
Cut-off -- The transistor acts like an open circuit. No current flows from collector to emitter. Active -- The current from collector to emitter is proportional to the current flowing into the base. Reverse-Active -- Like active mode, the current is proportional to the base current, but it flows in reverse.
