You need a TVS diode because many voltage regulators do not have the ability to sink current, nor can they respond fast ...

We have an amplifier. A simple FET radio receiver circuit showing FET biasing. The gate is biased at ground potential through the inductor, and the source is held above ground by the current in ...

It consists of a JFET based pre-amplifier ... screen shots provide signal analysis showing bias points and signal levels throughout the circuit. The choice of value for every component is ...
