When first learning about and building electronic circuits, the first things all of us come across are passive components such as resistors, capacitors, and inductors. These have easily-understandable ...

Engineers generally focus most attention on active components such as transistors, optoelectronic devices, ICs, and the like. In any design, however, the characteristics of passive devices ...

One can 3D print with conductive filament, and therefore plausibly create passive components like resistors. But what about active components, which typically require semiconductors? Researchers at ...
