A variety of logic-circuit techniques have been in use since the 1960s, when integrated logic first came into existence. In the beginning was Resistor-Transistor Logic (RTL). Then came ...

Logic signals have fallen from the 15V of the old CMOS 4000 series to 5V TTL (transistor-to-transistor logic) to modern CMOS levels of 3.3, 2.7, and 1.8V. Advanced processes use digital logic that ...

This may very well be the smallest homemade TTL CPU we’ve ever seen. Measuring at one square inch, this tiny chip boasts 40 connections, an 8-bit databus, a 16-bit address bus, a 64 kB memory space, ...

The fun part about logic gates is that there are so many ways to make them, with each approach having its own advantages and disadvantages. Although these days transistor-transistor logic (TTL) is the ...

Field-effect transistors based on carbon nanotubes have been shown to be faster and less energy consuming than their silicon counterparts. However, ensuring these advantages are maintained for ...

The panel industry is rapidly accelerating to higher resolution and a greater number of bits per colour. Breakthroughs in resolution and color are possible only when increasing the overall data rate ...

Only eight lithography masks to create a low-power custom logic chips, compared with 20+ for CMOS, is the claim of Nottingham-based fabless chip start-up ‘Search For The Next’ (SFN). As such, ...

Have you ever wanted to build your own minicomputer, but felt restricted by the available selection of https://www.pcworld.com/products/components/processors.html ...

Not content with your new, 1.4-billion-transistor Ivy Bridge processor? Maybe it runs too hot, or lacks the polygon-pushing powers that you require? Well, I've got just the thing for you: How about ...

Ladder logic uses switch or relay contacts to implement Boolean expressions. In years past, ladder logic was made possible with discrete relays and was sometimes termed “relay logic.” Today most ...
