Who would have thought that a circuit comprising only two 2-input NAND gates could be so complicated (or, should we say, “interesting”)? Up to this point (click here to see my earlier columns), the ...
Digital design with combinatorial gates like AND, OR, and NOT gates is relatively straightforward. In particular, when you use these gates to form combinatorial logic, the outputs only depend on the ...
LONDON — Hewlett-Packard Company (Palo Alto, Calif.) claimed Tuesday (Feb. 1) that its researchers have proven that a technology they invented could replace the transistor, the fundamental building ...
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 ...
What’s the weirdest computer you can think of? This one’s weirder. [Dr. Cockroach] figured out a way to create an inverting NOT gate from just one LED and two resistors (one being a photo-resistor).
Discover how a low-dropout linear regulator and a programmable logic device can replace microcontrollers for enable/disable functions, reducing power consumption to just microamperes. The enable ...
