Most amplifier and oscillator circuits were originally designed during the vacuum-tube era, and they have been converted to transistors and ICs with modifications that relate primarily to the ...

A simple AM transistor radio can be made with surprisingly few components, but for a circuit with a reasonable ... and two for the audio power amplifier, but it’s possible we’re not factoring ...

There is another family of transistors which have analogous ... to the gate voltage. We have an amplifier. A simple FET radio receiver circuit showing FET biasing. The gate is biased at ground ...
