Researchers from McMaster University and the University of Pittsburgh have created the first functionally complete logic gate—a NAND gate (short for "NOT AND")—in a soft material using only beams of ...

Multiplying two analog signals involves the use of analog multipliers, usually implemented by using log and antilog circuit blocks or the Gilbert cell. Today, the most common technique used to ...

Abstract: A gallium nitride (GaN) two-stage comparator based on complementary logic (CL) architecture is demonstrated and systematically investigated. The comparator features monolithically integrated ...

(a)Working principle of the spin logic device. (b) Transition among diverse magnetic configurations in this heterojunction. By manipulating the direction of the Oersted field, the SOT-induced ...

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 the ...

As the Trump administration dismantles foreign aid, Bill Gates, whose philanthropy is devoted to global health, is trying to talk to anyone with the president’s ear. Credit...Alex Welsh for The New ...

Researchers have devised a way to make computer vision systems more efficient by building networks out of computer chips’ logic gates. Networks programmed directly into computer chip hardware can ...

Apple today released Logic Pro 11.1 for Mac and Logic Pro 2.1 for iPad, adding new features for songwriting, producing, and mixing. There's a new Quantec Room Simulator plug-in that uses the original ...

Forward-looking: Semiconductors are essential for today's electronics, providing computational capabilities and the ability to control electric signals. They are also highly complex and costly, so ...

Why it matters: For decades, scientists have dreamed of building computer chips that use light instead of electricity to process information. While our current silicon chips are incredibly fast, ...
