Texas Instruments, Inc. (TI), U.S. manufacturer of calculators, microprocessors, and digital signal processors. The direct antecedent to the company, headquartered in Dallas, Texas, was founded by John Karcher and Eugene McDermott in 1930 to provide seismographic data for the petroleum industry. In 1958 Jack Kilby, a researcher at TI, coinvented the integrated circuit (IC), and in 1967 he invented the basic design for handheld calculators. In 1973 TI began to manufacture dynamic random-access memory (DRAM, commonly shortened to RAM) chips for use in computers, and in 1982 it introduced the single-chip digital signal processor (DSP), which it employs in cell phones, Global Postioning System (GPS) receivers, and adapters for computer networks.

NMOS transistorNegative-channel metal-oxide semiconductors (NMOS) employ a positive secondary voltage to switch a shallow layer of p-type semiconductor material below the gate into n-type. For positive-channel metal-oxide semiconductors (PMOS), all these polarities are reversed. NMOS transistors are more expensive, but faster, than PMOS transistors.

transistor Summary

Transistor, semiconductor device for amplifying, controlling, and generating electrical signals. Transistors are the active components of integrated circuits, or “microchips,” which often contain billions of these minuscule devices etched into their shiny surfaces. Deeply embedded in almost

integrated circuit Summary

Integrated circuit (IC), an assembly of electronic components, fabricated as a single unit, in which miniaturized active devices (e.g., transistors and diodes) and passive devices (e.g., capacitors and resistors) and their interconnections are built up on a thin substrate of semiconductor material

Dallas Summary

Dallas, city, Dallas, Collin, Denton, Rockwell, and Kaufman counties, seat (1846) of Dallas county, north-central Texas, U.S. It lies along the Trinity River near the junction of that river’s three forks, in a region of prairies, tree-lined creeks and rivers, and gentle hills. Its winters are mild
