An isolated comparator is fundamentally different from a standard comparator, and the comparison happens on the input side.

As a result, optocouplers are indispensable isolation devices in fields such as industrial control, home appliances, ...

Abstract: A thin-film phototransistor with a peak wavelength sensitivity of 420 nm was fabricated by integrating a bilayer hydrogenated-amorphous-silicon absorber with a nanocrystalline-silicon ...

Abstract: This paper presents a charge compensation phototransistor for high-dynamic-range CMOS image sensors (CIS). With a built-in charge compensation mechanism, the photoresponse of the proposed ...

The schematic diagram of the ultra-sensitive optical immunoassay platform, which comprises two pivotal components: one dedicated to establishing highly sensitive sandwich immunocomplexes for ...

Researchers from the Department of Physics in the College of Science and the James C. Wyant College of Optical Sciences, all at the University of Arizona, have demonstrated a way to manipulate ...

Researchers demonstrated a way to manipulate electrons in graphene using pulses of light that last less than one thousands trillionth (one quadrillionth) of a second. By leveraging a quantum effect ...

Researchers demonstrated a way to to manipulate electrons using pulses of light that last less than a trillionth of a second to record electrons bypassing a physical barrier almost instantaneously -- ...

What if ultrafast pulses of light could operate computers at speeds a million times faster than today's best processors? A team of scientists, including researchers from the University of Arizona, are ...

Scientists are exploring ultrafast light pulses to power computers that could run a million times faster than today's top processors. (Nanowerk News) What if ultrafast pulses of light could operate ...
