In order to help his friend prepare for a talk at DEFCON this weekend, [Craig] built an IR photodiode amplifier circuit. The circuit extended the detection range of the hack from a few inches to a few ...

Building a photodetector that works across a range of applications does not have to be complicated. In this post, we will break down a universal design concept that is flexible, practical, and ready ...

In this section we shall discuss the interface between a photosensor and its associated electronics. There are really just two photocell applications – light measurement, and the reception of ...

Follow these seven steps to successfully select a photodiode sensor and design an analog front end for a range of applications such as optical communications and light-based measurements. The energy ...

Panasonic's new Lumix DMC-GF5 incorporates the newly developed 12.1-megapixel Live MOS sensor which features high sensitivity signal processing. Both photodiode circuit and readout circuit are also ...

Imec, the nanoelectronics and digital technologies research hub, has announced the successful integration of a pinned photodiode structure into thin-film image sensors. With the addition of a ...

Most of us have Ethernet in our homes today. The real backbones of the Internet though, use no wires at all. Optical fibers carry pulses of light across the land, under the sea, and if you’re lucky, ...
