Transistors leverage multiple PN junctions. In a BJT, for example, an NPN transistor has a thin P-type base between an N-type emitter and N-type collector. A small current into the base-emitter ...

In this article, I'll show you how to make a simple touch-triggered switch. This is very useful for various electronic projects, from a simple bedside light to a flat panel touch keyboard. The circuit ...

(Nanowerk Spotlight) For new generation electronic appliances advanced nanoscale transistors are in demand which needs precise biasing of each device. These stringent biasing conditions can be relaxed ...

I'm playing with setting up some simple circuits, but none of my transistors seem to work. My latest attempt at making them do *something* goes as follows: I hooked up a 180 ohm resistor to the ...
