Walter Brattain. The introduction of the transistor is often considered one of the most important inventions in history. Transistors are broadly classified...

A transistor is a semiconductor device used to amplify or switch electrical signals and power. It is one of the basic building blocks of modern electronics...

junction transistor (BJT) is a type of transistor that uses both electrons and electron holes as charge carriers. In contrast, a unipolar transistor, such...

Transistor–transistor logic (TTL) is a logic family built from bipolar junction transistors. Its name signifies that transistors perform both the logic...

A transistor radio is a small portable radio receiver that uses transistor-based circuitry. Following the invention of the transistor in 1947—which revolutionized...

The field-effect transistor (FET) is a type of transistor that uses an electric field to control the flow of current in a semiconductor. It comes in two...

A transistor computer, now often called a second-generation computer, is a computer which uses discrete transistors instead of vacuum tubes. The first...

The transistor count is the number of transistors in an electronic device (typically on a single substrate or silicon die). It is the most common measure...

electronics, the metal–oxide–semiconductor field-effect transistor (MOSFET, MOS-FET, MOS FET, or MOS transistor) is a type of field-effect transistor (FET),...

are three types of unijunction transistor: The original unijunction transistor, or UJT, is a simple device that is essentially a bar of n-type semiconductor...
