These circuits will allow you to observe the operation of a transistor as an amplifier, just as Walter Brattain did at Bell Labs in the winter of 1947. In the first circuit, you’ll use the ...

Over the recent weeks here at Hackaday, we’ve been taking a look at the humble transistor ... We have an amplifier. A simple FET radio receiver circuit showing FET biasing.

As with many inventions, two people had the idea for an integrated circuit at almost the same time. Transistors had become ... build what they called "unitary circuits" and they also applied ...

Can you do the same thing with electronic circuits? The answer–perhaps not surprisingly–is yes. Consider this simple common emitter amplifier ... a normal silicon transistor, this should ...
