If you cultivate an interest in building radios it’s likely that you’ll at some point make a simple receiver. Perhaps a ...

This video explains how transistors work as switches and amplifiers in electronic circuits. Transistors control the flow of ...

Photocouplers optically links, via transparent isolating material, a light emitter and a photodetector. Used as an interface between circuits with different ground potentials, photocouplers replace ...

The recent EDN article of Bruce Trump () on the input impedance of an op-amp circuit took into account the single-pole roll-off of its loop gain. He showed with a simple derivation how the equivalent ...

The basic rules by which chips are being designed could be wrong, physicists have warned. Researchers at the US National Institute of Science and Technology have warned that a flaw exists in ...

IBM announced today that it has developed a way to improve the transistor--a move which its describes as the "first fundamental change to basic transistor in forty years". Together with other ...
