Manufacturing companies, particularly those that mass-produce electronic circuits, work pretty much around bipolar junction transistors, like PNP and NPN. However, choosing between these two BJTs can ...

Transistors are an indispensable building block in electric appliances, where they amplify weak electric currents. Now researchers have developed a new type of transistor that is 50 times more energy ...

WE have considered in some detail the problem of using germanium and silicon transistors as choppers in thermocouple-amplifier and other low- and medium-impedance applications. In the past, several ...

For circuit designs that use complementarybipolar transistors,you sometimes need to sort the NPNand PNP transistors to have matchingdc-current gains (β). One example of acircuit requiring matching is ...

The first transistor was about half an inch high. That's mammoth by today's standards, when 7 million transistors can fit on a single computer chip. It was nevertheless an amazing piece of technology.

Matching a sensor interface with a programmable logic converter or controller hardware that can accept only one type of input—npn or pnp—can be difficult. The last-stage modification circuit described ...

At the heart of modern electronics are transistors, which act like valves to direct the flow of electrons. Now researchers at the University of California at Berkeley have created the first ...
