This, Purdue professor Andrew Weiner points out, is the most fundamental part of a logic circuit. The passive optical diode developed at Purdue makes this possible with light instead of electrons.

The researchers created simple diode-based AND/OR logic gates from these circuits and incorporated them into pulse modulators, which can encode information by switching one input signal on or off ...

Posted: Sep 01, 2014: An all-carbon optical diode for photonic computing (Nanowerk Spotlight) Silicon transistors have been made smaller year after year, but they are approaching a point of physical ...

Researchers have invented a new organic polymer tunnel diode -- an electronic component that could one day lead to plastic computer memory and plastic logic circuits on computer chips. Today ...

Sure, these transistors are operated at their conduction extremes (which is why they are called “digital”), but during the logic state transition they're pure analog. By adding a few passive ...

At this week's IEEE International Electron Devices Meeting (IEDM 2012), imec presented the world-first ultra-high frequency Schottky diode based on amorphous IGZO (Indium-Gallium-Zinc Oxide) as ...

So additional key factors to be considered are: In this case the universal op amp LM358 plus one Zener diode, one transistor and 17 passive components are used to control the output power. The circuit ...

This circuit enables effective power delivery for DC-biased superconducting logic and quantum circuits, supporting miniaturization, reduced power consumption, and lower electromagnetic noise in ...
