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 ...

Transistor-transistor-logic or TTL parts have been around for a long time and now and then, I still seem to run across this or that “thing” where they've been designed in, not necessarily in the ...

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 ...

Timing relationships between signals are critical to reliable operation of digital designs. With synchronous designs, the timing of the clock signal relative to data signals is especially important.

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 ...

I fear the topic of this column is poised to unleash a tsunami of controversy. My engineering accomplice Joe Farr says that this is one of those topics that, when presented to 10 different engineers, ...

Recently in material science news from China we hear that [Hailin Peng] and his team at Peking University just made the world’s fastest transistor and it’s not made of silicon. Before we tell you ...
