Definition of "transistor" |
A semi-conductor device capable of amplification. / A semi conductor device capable of amplification. / A transistor is a semiconductor device used to amplify and switch electronic signals and electrical power. It is composed of semiconductor material with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor's terminals changes the current through another pair of terminals. Because the controlled output power can be higher than the controlling input power, a transistor can amplify a signal. Today, some transistors are packaged individually, but many more are found embedded in integrated circuits. / The transistor, invented by three scientists at the Bell Laboratories in 1947, rapidly replaced the vacuum tube as an electronic signal regulator. A transistor regulates current or voltage flow and acts as a switch or gate for electronic signals. A transistor consists of three layers of a semiconductor material, each capable of carrying a current. A semiconductor is a material such as germanium and silicon that conducts electricity in a "semi-enthusiastic" way. It's somewhere between a real conductor such as copper and an insulator (like the plastic wrapped around wires). / Signaling System 7 is a system that puts the information required to set up and manage telephone calls in a separate network rather than within the same network that the telephone call is made on. / term derived from "transfer resistor." Semiconductor device that can be used as an amplifier or as an electronic switch. |
