The definition of a transistor is an electronic device that works by controlling the flow of the electrical current.

An example of a transistor is something combined in large numbers with microcircuits into a single circuit board and used in a computer.

A solid-state, electronic device, composed of semiconductor material, as germanium, silicon, etc., that controls current flow without use of a vacuum: transistors are similar in function to electron tubes, but have the advantages of being compact, long-lived, and low in power requirements.

An electronic device that controls the flow of an electric current, most often used as an amplifier or switch. Transistors usually consist of three layers of semiconductor material, in which the flow of electric current across the outer layer is regulated by the voltage or current applied at the middle layer. Having replaced the vacuum tube, transistors are the basis of much modern electronic technology, including the microprocessor.

In the analog world of continuously varying signals, a transistor is a device used to amplify its electrical input. In the digital world, a transistor is a binary switch and the fundamental building block of computer circuitry. Like a light switch on the wall, the transistor either prevents or allows current to flow through. A single modern CPU can have hundreds of millions or even billions of transistors.Made of Semiconductor MaterialThe active part of the transistor is made of silicon or some other semiconductor material that can change its electrical state when pulsed. In its normal state, the material may be nonconductive or conductive, either impeding or letting current flow. When voltage is applied to the gate, the transistor changes its state. To learn more about the transistor, see transistor concept and chip. See active area, phototransistor and High-K/Metal Gate.

A contraction of trans-resistor, a transistor is a solid-state active device that controls current flow. A transistor comprises a semiconducting material, such as silicon or germanium, in three electrode regions with two junctions.The regions are alternately doped positive-negative-positive or negative-positivenegative in a semiconducting sandwich, so to speak. One outer region serves as the collector, the inner region as the base, and the other outer region as the emitter. The collector circuit collects power from the external power source, the base acts like a control electrode, and the emitter emits the outbound signal. Small signals applied between the base and the emitter control the larger currents and power from the collector, with a small change in the signal applied to the base producing a large and rapid change in the current flowing through the entire component. A transistor can operate linearly, like an audio amplifier, or like a switch, rapidly opening and closing an electronic gate. A transistor can act on a signal to perform a variety of functions such as amplification, rectification, modulation or demodulation, and buffering.The transistor was invented by William Shockley, John Bardeen, and Walter Britain of AT&T Bell Telephone Laboratories, in 1947, and quickly replaced the electron tube, or vacuum tube.As a result of the 1956 Consent Decree, AT&T was forced to license the patented transistor technology to any company for $25,000. General Electric, IBM, Sony, and Texas Instruments are but a few of the companies that wrote a check. Large numbers of transistors are frequently interconnected with microcircuits and baked into a single integrated circuit, many of which can exist on a single circuit board in an electronic device such as a computer, switch, or router. See also amplifier, buffer, Consent Decree, current, modulation, patent, power, rectifier, and signal.
