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 the 5K resistor ...

To illustrate a basic diode switch, we’ve prepared a couple of simplified circuit diagrams. The first shows the anode tied to ground through R1 and the cathode tied to the Vcc power rail. The ...

Diodes, one-way current conductors, are used for voltage regulation, AC/DC conversion, and circuit protection. Forward-biased at 0.6V, conduct current, reverse bias blocks it.
