This intelligent electronic lock circuit is built using transistors only. To open this electronic lock, one has to press tactile switches S1 through S4 sequentially. For deception you may annotate ...

Explains the principles of transistor switching circuits, highlighting their role in electronic computers. It contrasts transistors with vacuum tubes, emphasizing that transistors function as ...

As with many inventions, two people had the idea for an integrated circuit at almost the same time. Transistors had become commonplace in everything from radios to phones to computers, and now ...

If you’ve spent any time on hackaday.io, you may have noticed that more than a few denizens of the site are fans of “alternative” electronic logic. Aiming to create digital circuits from such things ...

The often-quoted Moore 's Law says that we can expect processors to double in capacity every 18 months. And that has held true. Now computer scientists warn that - without some significant ...

The newly developed logic circuits are equipped with diamond-based MOSFETs (metal-oxide-semiconductor field-effect-transistors), and they have two different operation modes. The different modes are a ...

The following automatic battery-charger design is created with a circuit that could qualify as the simplest window comparator ever built around a single transistor (see the figure). It starts charging ...

Yesterday morning I ran across what sounded like an interesting story from Hewlett-Packard's labs that seemed to involve a possible transistor replacement, nanotechnology, and the indefinite ...

Transistors, the building blocks of modern electronics, are typically made of silicon. Because it's a semiconductor, this material can control the flow of electricity in a circuit. But silicon has ...
