DNA is a reliable biomolecule with which to build molecular computation systems. DNA logic circuits (diffusion-based) have shown good performance regarding scalability and correctness of computation.

Logic gates are the bricks and mortar of digital electronics, implementing a logical operation on one or more binary inputs to produce a single output. These operations are what make all computations ...

Researchers have built logic circuits, the heart of all electronic gadgets, on molybdenum disulfide films that are two molecular layers thick (Nano Lett., DOI: 10.1021/nl302015v). The devices are the ...

Since 1972, scientists have known there are four basic circuit components, but if you’ve spent any time in an electrical engineering classroom, you probably only have experience with three: capacitor, ...

Optical logic circuits employing microring resonators represent a rapidly evolving area within photonic integrated circuits, where miniaturised ring structures facilitate the realisation of high-speed ...

Consider the logic circuit in the figure shown. Determine the Boolean expression at the circuit output and simplify it. From the simplified Boolean expression, find which logic gate is redundant in ...

In the world of engineering, "noise" – random fluctuations from environmental sources such as heat – is generally a bad thing. In electronic circuits, it is unavoidable, and as circuits get smaller ...

Making sound with digital logic usually calls for a Digital to Analog converter. Building one can be very simple, and the sound quality out of an R-2R Ladder is actually pretty good. In the last ...

In a proof-of-concept study, researchers have created self-assembled, protein-based circuits that can perform simple logic functions. The work demonstrates that it is possible to create stable digital ...

The circuit was designed to create a handy logic probe that can show off the logic states for high, low and pulsing outputs with the use of CMOS 4001 integrated circuit. Logic Probe – a handheld probe ...
