a solid-state semiconductor device, with three terminals, which can be used for amplification, switching, voltage stabilization, signal modulation, and many other functions
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)
Transistors are tiny electrical devices that can be found in everything from radios to robots They have two key properties: 1) they can amplify an electrical signal and 2) they can switch on and off, letting current through or blocking it as necessary
a semiconductor used in many electronic circuits It serves as a switch, an amplifier or detector 2
A three leaded device (Collector, Base, Emitter) used for amplifying or switching Also called a bi-polar transistor to distinguish it from Field Effect Transistor etc
A semiconductor device used in electronic circuits to manipulate electrical signals
A semiconductor device used in amplifiers, oscillators, and control circuits in which current flow is modulated by voltage or current applied to electrodes Most transistors are based on the use of silicon
A device incorporating semiconductor material and suitable contacts capable of performing electrical functions (such as voltage, current or power amplification) with low power requirements
A semiconductor device consisting of three or four layers used for switching or amplification at frequencies ranging from direct-current to ultra-high
a solid-state of an electronic device that is used to control the flow of electricity in electronic equipment (it consists of a small block of a semiconductor)
Transistors made from purified silicon These are usually formed in a silicon wafer using lithography and various thin film deposition steps They are usually CMOS, or Complementary Metal Oxide Semiconductor, transistors (this is the type used ubiquitously in computers today) Bipolar transistors are also made, especially for high-speed communications devices
An electronic component used as a switch to open and close with extreme speed Transistors have replaced the vacuum tube due to their reliability, long life, and much higher switching speed
An active semiconductor device capable of providing power amplification Transistors have three or more terminals
Or tranfer resistor A semiconductor component that acts like a switch, controlling the flow of an electric current Transistors are incorporated into modern microprocessors by the million
A transistor or a transistor radio is a small portable radio. Solid-state semiconductor device for amplifying, controlling, and generating electrical signals. Invented at Bell Labs (1947) by John Bardeen, Walter H. Brattain, and William B. Shockley, it displaced the vacuum tube in many applications. Transistors consist of layers of different semiconductors produced by addition of impurities (such as arsenic or boron) to silicon. These impurities affect the way electric current moves through the silicon. Transistors were pivotal in the advancement of electronics because of their small size, low power requirements, low heat generation, modest cost, reliability, and speed of operation. Single transistors were superseded in the 1960s and '70s by integrated circuits; present-day computer chips contain millions of transistors. Today transistors perform many different functions in nearly every type of electronic equipment
a solid-state electronic device 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
