Plasma science has grown over the past few decades in scope and importance, and plasmas are now used in many industries ...

This study proposes a novel light-emitting diode (LED) driver circuit that stabilizes the lighting output without a photodiode. The LED driver circuit is composed of a self-alignment circuit to ...

Avalanche photodiodes (APDs) for ultra-sensitive infrared detection at eye-safe wavelengths are built around compound ...

A 0.25 /spl mu/m technology CMOS image sensor employs a 4.2 /spl mu/m pitch pinned-photodiode pixel. A column amplifier and digital domain processing reduce the fixed pattern noise to 55 /spl mu/V.

In what could be a major leap forward in imaging technology, Apple has quietly patented an advanced image sensor that boasts ...
