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. General Electric, IBM, Sony, and Texas Instruments are but a few of the companies that wrote a check.

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. What is a Transistor History of Transistors The Transistor was Invented in 1948 at Bell Telephone Laboratories From Germanium to Silicon Functions of a. A transistor can operate linearly, like an audio amplifier, or like a switch, rapidly opening and closing an electronic gate. 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.
The collector circuit collects power from the external power source, the base acts like a control electrode, and the emitter emits the outbound signal.

notes for transistor The transistor is the basic device used in miniaturized electronic systems, such as portable radios, or as a fast switch in computers. It is normally made from silicon or other semiconductors. One outer region serves as the collector, the inner region as the base, and the other outer region as the emitter. The first is as an amplifier, turning a small electrical signal into a larger and more powerful one. transistor An electronic device that can work as an amplifier, transforming weak electrical signals into strong ones. 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. A contraction of trans-resistor, a transistor is a solid-state active device that controls current flow. A transistor is an electronic component that acts like a valve to control the amount of current passing through it.
