The scientific method in practice I once spent three months troubleshooting a problem that started off with a fairly straightforward symptom. A prototype pulse oximeter had occasional voltage glitches ...

Although advances in photonics and electronics are making it easier and cheaper to implement a light detection and ranging (LIDAR) system, the analog front-end receiver interface still presents many ...

Geiger-mode avalanche photodiodes (GM-APDs) are highly sensitive light detectors, capable of detecting single photons. Photons of certain wavelengths, when absorbed by photodiodes, generate ...

TOKYO--(BUSINESS WIRE)--Kyoto Semiconductor Co., Ltd. (President and CEO Tsuneo Takahashi, Head office: Fushimi-ku, Kyoto city), a leading optical device solution manufacturer with world-class ...

Electrical and computer engineers have developed an avalanche photodiode that achieved record performance and has the potential to transform next generation night-vision imaging and Light Detection ...

Detecting infrared light is critical in an enormous range of technologies, from remote controls to autofocus systems to self-driving cars and virtual reality headsets. That means there would be major ...

1. This circuit uses a JFET to bootstrap the cathode of the photodiode. It eliminates the effect of diode resistance and capacitance. This improves bandwidth and reduces noise, but puts a dc voltage ...

Imec, the Leuven, Belgium-based research and innovation hub in nano- and digital technologies, has announced the successful integration of a “pinned photodiode structure” in thin-film image sensors.
