| | | | | I was recently doing some background reading for a project and came across a cool concept called Gyrators. Sometimes also called synthetic inductors, they are circuit elements that emulate the behaviour of inductors using active components like opamps or transistors along with capacitors and resistors. The concept behind a gyrator is that it converts impedance, [...] | |

| | | | | Inventing the TransistorScientists in the 1920s proposed building amplifiers from semiconductors. But they didn't understand the materials well enough to actually do it. In 1939, William Shockley at AT&T's Bell Labs revived the idea as a way to replace vacuum tubes.Under Shockley's direction, John Bardeen and Walter Brattain demonstrated in 1947 the first semiconductor amplifier: the point-contact transistor, with two metal points in contact with a sliver of germanium. In 1948, Shockley invented the more... | |
