Transistors

Some articles on transistors, transistor:

Sonotone 1010
... aid, introduced on 29 December 1952, was the first commercial product to use transistors, which had been invented five years earlier in 1947 ... vacuum tubes as input stages and a single transistor as the output stage this was required because the transistors at the time produced too much electrical noise ... Even using one transistor considerably extended battery life, lowering the operating cost of the unit ...
Manchester Computers - Transistor Computer
... Webb, were assigned to the task of designing and building a machine using the newly developed transistors instead of valves ... Initially the only devices available were germanium point-contact transistors, less reliable than the valves they replaced but which consumed far less power ... The 1955 version used 200 transistors, 1,300 solid-state diodes, and had a power consumption of 150 watts ...
Alloy-junction Transistor
... The germanium alloy-junction transistor, or alloy transistor, was an early type of bipolar junction transistor, developed at General Electric and RCA in 1951 as an ... The usual construction of an alloy-junction transistor is a germanium crystal forming the base, with emitter and collector alloy beads fused on opposite sides ... several types of improved alloy-junction transistors developed over the years that they were manufactured ...
Multigate Device - Varieties - Tri-gate Transistors
... Tri-gate or 3-D Transistor fabrication is used by Intel Corporation for the nonplanar transistor architecture used in Ivy Bridge processors ... These transistors employ a single gate stacked on top of two vertical gates allowing for essentially three times the surface area for electrons to travel ... Intel reports that their tri-gate transistors reduce leakage and consume far less power than current transistors ...
The First Transistor Computer
... The University of Manchester's experimental Transistor Computer was first operational in November 1953 and it is widely believed to be the first transistor computer to come into operation ... There were two versions of the Transistor Computer, the prototype, operational in 1953, and the full-size version, commissioned in April 1955 ... The 1953 machine had 92 point-contact transistors and 550 diodes, manufactured by STC ...
