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.

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 ...

By adding a few passive components, you can make circuits such as level converters, frequency multipliers, phase detectors, line drivers, and pulse changers. Take the simplest form of a passive ...

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. March 29, 1961 - LOGICAL ...

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 ...

Integrated Driver Circuit Figure 2 shows a solution with a dedicated APC laser driver IC 4 for CW operation up to 300 mA from a 2.4 to 15-V supply voltage. It requires only four additional passive ...

This circuit was created to reduce the heat dissipated by a power-supply “or” diode in a redundant 50-V supply. We can replace an “or” diode with an n-channel power FET.
