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 ...

Funding worth £1.34million has been awarded to semiconductor specialist Diamond Microwave Devices and its partners by Government funded body the Technology Strategy Board. The investment, through the ...

Sometimes we need a transistor with a different characteristic than the normal one for max voltage and current of the collector, maximum power dissipation and amplification. This can be done by using ...

This 2-bit adder was a lot of work to build. It uses a total of thirty-six 555 timers and it does have the option of adding or subtracting numbers. It’s a rather unorthodox use of the part, depending ...

The transistor is probably the most important invention in electronic engineering and the basis for nearly all integrated circuits (ICs). The transistor is a three-terminal electronic device that can ...

As integration density continues to increase, it becomes even more difficult to make electronic components for complex applications in nanoelectronics — such as navigation systems or computer ...

The realization of free-standing probes with nanoelectronic device tips requires bridging length scales from the nanoscopic to the macroscopic in a manner that yields robust electrical and mechanical ...
