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.

Raghavendra, Clemson Nanomaterials Center) A 'passive' optical diode functioning in an all-carbon on-chip ... our device could offer unprecedented speed levels in photonic logic circuits," Rao ...

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 ...

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 ...

Philco is expected to be in production shortly on preliminary transistor-diode “logic ... circuit modules may be made by vacuum deposition techniques or by combining microresistors and other ...

The diode is the fundamental block in the power supply generator of passive, i.e., battery-less ... of a functioning bidirectional thin-film RFID circuit (at ISSCC2012), are critical research ...

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 ...

A Schottky diode is useful for connecting multiple batteries or dc power supplies to a load. Here is a circuit for doing ... enabling passive cooling without a fan.
