The classic transistor amplifier circuit then has a pair of ... but this simplest of circuits should be enough to understand its operation. How then does one arrive at the values for the various ...

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.
