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.

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 ...

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 … ...

Here we demonstrate all-passive on-chip optical AND and NAND logic gates made from a directional emitting cavity connecting two ultrasmall photonic crystal heterojunction diodes. The measured ...

This is the large-scale proof of concept for the unique family of logic circuits [Ted] came up with that only uses bog-standard diodes to construct arbitrary digital logic.

"We expect to increase the nonreciprocity factors of the optical diodes to >10 by changing the non-linear optical properties of graphene by doping. With ultrafast carrier dynamics of nanocarbons, ...

Input current for a passive PFC circuit is insensitive to changes in the output ripple - so it requires a smaller inductance than previous circuits.

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 ...

Here’s a blast from the past as we reprint our news from NYC’s 1961 IRE show—the first integrated logic circuits in TO-5 and TO-18 cans are being announced.

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 ...
