(Courtesy: Yi Zhang/Aalto University) Light-based optical logic gates operate much faster than their electronic counterparts and could be crucial for meeting the ever-growing demand for more efficient ...

Digital gates are ... present in the data stream, a timed tri-state pump-up or pump-down pulse would be preferable unless the RC time constant is made very long relative to the run of consecutive bits ...

This Design Idea describes a new class of logic gates, which we have named resistor-FET-logic, aka “RFL.” How do we know it is new? While FET switches are common today, we have been unable to find a ...

We’ve seen computers and computer gates built out of things as diverse as marbles, relays, and — of course — transistors. However, there are logic gate systems that use a property of moving ...

A research team from Skoltech and the University of Wuppertal in Germany determined that an all-optical universal logic gate that was previously ... compare experimental data from various trials.

Until now, DNA computers – which use strands of DNA molecules to store and process data – were essentially ... have developed new “see-saw” logic gates that let them automate the process ...
