In the early days, PNP bipolar transistors were common, but the bulk of circuits you see today use NPN transistors. As [Aaron Danner] points out, many people think PNP transistors are “backward” but ...

The following automatic battery-charger design is created with a circuit that could qualify as the simplest window comparator ever built around a single transistor (see the figure). It starts charging ...
The first transistor was successfully demonstrated at Bell Laboratories in Murray Hill, New Jersey, in 1947. This three-terminal device has spawned many of the electronics devices that make possible ...
