Lastly its around you thinking that makes the $150 EDN cheque keep coming. Happy birthday on this 21st line with glory in the future you shine. Important device that you are alone setting for all intelligent life a milestone. Millions of you on a chip monolithic crunch his computation without a hick. So important was your invention you have given humans a chance against extinction. Blowing life into all his complex machinery you take him towards progressive certainty. Ever ready you for any fight is there a rival technology in sight? With vacuum tube behind I guess you are the dearest device of mankind. Thank your size so small there is today computer in pockets of all. For you can project the multi storied power monster ENIAC on thumb nail. How shall your size, power and efficiency in the contemporary times I hail. That can be likened to with those of the Brahma Vishnu Maheshwara deities. For under your guidance the charge carriers in emitter base collector have duties. Number of terminals you have are three each one imitates a celestial deity. Your operation was simple, age longer, size smaller and the dominion ever larger. Running cool and wise unlike the tube didn’t have the scorching sun inside. Your immediate power consumption was insignificant and the amplification you produced was sufficient. So came into being the transistor destined to be the vacuum tube Vanquisher. Compel d man looked for new device that would bring limitation to its demise. Vacuum tubes with hot heater of high wattage wouldn’t work without high voltage. For their creation, maintenance and destruction had put upon him severe technological limitation. Mankind with vacuum tubes was buried under the tyranny of colossal power consumption. ![]() Should you see an error, please notify us.Įditor’s note: This article was originally posted on Decemand edited on December 16, 2018.Ī few lines I wrote for the transistor on its birthday: EDN strives to be historically accurate with these postings.

Transistor inventors Bardeen, Brattain (standing L-R), and Shockley (seated) on the cover of Electronics magazine in Sept 1948. The team demonstrated the discovery a week later on December 23, often considered the date the transistor was invented.īell Labs publicly announced the device at a Jpress conference, where a spokesman claimed that “it may have far-reaching significance in electronics and electrical communication.” The voltage on one contact modulated the current flowing through the other, amplifying the input signal up to 100 times. They applied two closely-spaced gold contacts held in place by a plastic wedge to the surface of a small slab of high-purity germanium. It wasn’t until Decemthat the first successful test of their semiconductor amplifier occurred. Bardeen and Brattain’s first point-contact transistor. ![]()
