Thus the three basic bipolar transistor circuit configurations have equivalents ... There are equivalent P-channel devices, just as there are PNP and NPN bipolar transistors.

Just like with NPN and PNP transistors ... Speaking of the Pinecil, it uses an unorthodox driving circuit – it has an NPN transistor, but its base driven through a capacitor, so that only ...

The sandwich transistor was William Shockley's brainchild. It's also called the junction transistor. While the rest of the lab was busy researching Bardeen and Brattain's point-contact transistor ...
