When a CMOS circuit is in an idle state there is still some static power dissipation–a result of leakage current through nominally off transistors. Both nMOS and pMOS transistors used in CMOS logic ...

Using digital logic gates such as AND, OR, XOR, NOT, NAND, NOR, and XNOR and other related logic functions is often the foundation for defining the relationship between electrical signals and how they ...

Fig 1. A typical CMOS input circuit comprises a “P” and “N” transistor. One is fully “on” for logic high, and the other is “on” for a logic low. Fig 2. When a CMOS input pin is at logic high or low ...

Before we plunge headfirst into the fray with gusto and abandon (and aplomb, of course), let’s remind and reassure ourselves that—although the following discussions focus on the devices and ...

Lawrence Livermore National Laboratory scientists and engineers combed mechanical computing with 3D printing to create “sentient” materials that respond to changes in their surroundings, even in ...

YouTuber Steve Mould has created a great demonstration of computer logic gates using water, tubes, and 3D printed components. This innovative approach provides a tangible and visual way to understand ...
